Everyone (with rare exceptions) is born with a set of 23 pairs of chromosomes. We inherit half from our mother and the other half from our father.<\/p>\n\n\n\n<p>Two of those pairs are usually sex chromosomes (XX in females and XY in males), and the remaining 22 pairs of chromosomes are autosomal or autosomes. An ancestry autosomal DNA test is rich in information that unravels your autosomal DNA testing for genealogy and can determine ethnic ancestry.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-1.jpg\" alt=\"Autosomal DNA test\" class=\"wp-image-18431\" width=\"440\" height=\"294\" srcset=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-1.jpg 352w, https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-1-300x200.jpg 300w\" sizes=\"(max-width: 440px) 100vw, 440px\" \/><figcaption class=\"wp-element-caption\">DNA Genotyping and Sequencing. <a href=\"https:\/\/unsplash.com\/@nci?utm_source=unsplash&amp;utm_medium=referral&amp;utm_content=creditCopyText\">National Cancer Institute<\/a>.

This is the portion that autosomal DNA tests decode and analyze. Interestingly, 99.9% of this information is identical in every human being. It is the small variations that determine your traits and genetic makeup, including the ones you inherit.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-autosomal-dominant-vs-autosomal-recessive\"><strong>Autosomal dominant vs autosomal recessive<\/strong><\/h2>\n\n\n\n<p>Let\u2019s quickly break down the types of autosomes to understand better how the tests work. Within the 22 autosomes, there are two categories of genes or conditions that are passed onto the offspring by their parents. These are autosomal dominant and autosomal recessive.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-autosomal-dominant\">Autosomal dominant<\/h3>\n\n\n\n<p>If a given condition (a trait or a disease) is dominant, the offspring only needs one gene from one parent to have the trait or condition.&nbsp;<\/p>\n\n\n\n<p>Here are two inheritance patterns:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You have the trait or condition if you inherit the gene from one of your parents only.&nbsp;<\/li>\n\n\n\n<li>You do not have the condition or trait if both of your parents pass on an unaffected gene.<\/li>\n<\/ul>\n\n\n\n<p>For an autosomal dominant condition to manifest, you only need to inherit it from one of your parents. You can still get an autosomal dominant disease even if none of your parents has it when a mutation occurs.&nbsp;<\/p>\n\n\n\n<p>Some common autosomal dominant disorders include Marfan syndrome and Huntington\u2019s disease.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-autosomal-recessive\">Autosomal recessive<\/h3>\n\n\n\n<p>An autosomal recessive trait or condition will only manifest if you inherit it from both of your parents. A very common autosomal recessive disease is cystic fibrosis. This means that you need both of your parents to pass it on to you to have the condition.&nbsp;<\/p>\n\n\n\n<p>If one of your parents passes on to you an affected gene but the other passes on an unaffected one, you still carry this gene, of course, but you do not manifest it. You are, therefore, a carrier. If you have children, you can pass on this affected gene to them.&nbsp;<\/p>\n\n\n\n<p>There are three ways in which an autosomal recessive trait or condition can happen:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You inherit an affected gene from one parent but not the other. You do not have the condition, but you are a carrier.<\/li>\n\n\n\n<li>You do not inherit any affected genes from any of your parents. No condition, not a carrier.<\/li>\n\n\n\n<li>You inherit an affected gene from both parents. You manifest the trait or condition.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-autosomal-dna-testing-how-does-it-work\"><strong>Autosomal DNA testing: How does it work?<\/strong><\/h2>\n\n\n\n<p>Autosomal DNA testing will look into these 22 pairs of autosomes. Through an analysis, an autosomal DNA test can determine who are your close relatives and even go several generations back and also determine your most common ancestry.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" width=\"443\" height=\"295\" src=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-3.jpg\" alt=\"An artistic rendition of DNA databases - an important part of autosomal DNA testing\" class=\"wp-image-18447\" srcset=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-3.jpg 443w, https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-3-300x200.jpg 300w\" sizes=\"(max-width: 443px) 100vw, 443px\" \/><figcaption class=\"wp-element-caption\">Autosomal DNA testing can be used to determine predispositions and find relatives. <a href=\"https:\/\/pixabay.com\/illustrations\/medicine-biology-healthcare-dna-163707\/\">Pixbay<\/a>. <a href=\"https:\/\/pixabay.com\/users\/publicdomainpictures-14\/?utm_source=link-attribution&amp;utm_medium=referral&amp;utm_campaign=image&amp;utm_content=163707\">PublicDomainPictures<\/a>.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-the-process\">The process<\/h3>\n\n\n\n<p>The first step to an autosomal DNA test is to provide a DNA sample through <a href=\"https:\/\/nebula.org\/blog\/how-to-get-a-dna-test\/\">DNA kits<\/a>. You do this with a spit, cheek swab, or blood. The sample is sent to a laboratory that will sequence your <a href=\"https:\/\/nebula.org\/blog\/history-of-the-dna-model\/\">DNA<\/a> and provide the autosomal DNA results from the genetic test.<\/p>\n\n\n\n<p>Once this is done, the facility will analyze the autosomal dna test results through a chromosome browser and compare them with other testers\u2019 results. This is why the size of the genetic pool of a company is essential.&nbsp;<\/p>\n\n\n\n<p>Within your DNA, scientists can now look across it, finding important positions or markers. The closer two relatives are, the more similar these markers will be. The company can then compare your DNA against their database to find close relatives. This information can also be used to trace back <a href=\"https:\/\/nebula.org\/blog\/ethnicity-test\/\">ethnicity<\/a> several generations back.&nbsp;&nbsp;<\/p>\n\n\n\n<p>The autosomal DNA delivers a lot more genetic information than Y-chromosome, and mitochondrial DNA testing (<a href=\"https:\/\/nebula.org\/blog\/mtdna-test\/\">mtDNA tests<\/a>) because there is a lot more information to be found in all 22 autosomal chromosomes.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-who-should-take-the-test\">Who should take the test?<\/h3>\n\n\n\n<p>There are two reasons why people take an autosomal DNA test:&nbsp;<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>To find out where their ancestors from 500 to 1000 years ago might have lived.<\/li>\n\n\n\n<li>To find existing family members.&nbsp;<\/li>\n<\/ol>\n\n\n\n<p>Additionally, if there is a condition running in your family for generations, this test can confirm if you inherited the disease and your chances of having it.&nbsp;<\/p>\n\n\n\n<p>The results obtained are more relevant to family ties than mtDNA or Y-DNA because it entails genetic information shared by all the members of your family. A Y-chromosome DNA test only traces the paternal lineage, and mtDNA only traces the maternal line through your mother&#8217;s side.<\/p>\n\n\n\n<p>Everyone in your family can take an autosomal DNA test, regardless of age and gender. They provide information about your current relatives and recent genetic history. It is also an accurate way of finding new members from older generations.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-4.jpg\" alt=\"A multi-generational photographic\" class=\"wp-image-18455\" width=\"522\" height=\"365\" srcset=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-4.jpg 382w, https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-4-300x210.jpg 300w\" sizes=\"(max-width: 522px) 100vw, 522px\" \/><figcaption class=\"wp-element-caption\">Autosomal DNA testing can find relatives from many generations. <a href=\"https:\/\/unsplash.com\/@anniespratt?utm_source=unsplash&amp;utm_medium=referral&amp;utm_content=creditCopyText\">Annie Spratt<\/a>.

When you test both parents, you can determine what section of your genes you inherited from which parent.&nbsp;<\/p>\n\n\n\n<p>Test your siblings, too, as they may have inherited some DNA that you did not. Your uncles and aunts will have some DNA that your parents did not inherit from your grandparents.&nbsp;<\/p>\n\n\n\n<p>Next would be to test your other close relatives. We are talking about first to third cousins to get a better representation, although testing second cousins delivers a maximum return. Your cousins share a DNA set from your grandparents that your parents did not pass on to you.&nbsp;&nbsp;<br>Nebula Genomics decodes 100% of your autosomes with our <a href=\"https:\/\/nebula.org\/whole-genome-sequencing\/\">30X Whole Genome Sequencing<\/a> test kit. Plus, with our partnership with YFull, you can trace your ancestors from many years behind and discover if you share ethnicity markers. You can also find out whom you have common ancestors with, where lived and where they moved to through generations.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-transferring-dna-test-results\">Transferring DNA test results<\/h3>\n\n\n\n<p>Perhaps you got your DNA test results from another company and would like to compare it against a more extensive DNA database. Testing companies such as <a href=\"https:\/\/nebula.org\/blog\/23andme-login-sign-in\/\">23andMe<\/a> and<a href=\"https:\/\/nebula.org\/blog\/ancestry-login\/\"> Ancestry<\/a> provide your raw DNA information along with your results. We are continuously adding partners and next, we will take in your raw DNA from <a href=\"https:\/\/nebula.org\/blog\/living-dna-review\/\">Living DNA<\/a> and other testing companies.&nbsp;<\/p>\n\n\n\n<p>You can easily <a href=\"https:\/\/nebula.org\/free-dna-upload-analysis\/\">upload raw DNA results to Nebula<\/a> to get broader results of your ancestors, relatives, and DNA markers\u2019 connections to other populations in the United States and worldwide.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-accurate-is-the-autosomal-dna-test\"><strong>How accurate is the autosomal DNA test?<\/strong><\/h2>\n\n\n\n<p>This test type is very <a href=\"https:\/\/nebula.org\/blog\/how-accurate-are-dna-tests\/\">accurate<\/a> to confirm parent\/child relationships and relationships up to a second cousin. It can also help identify and find most of your third cousins. Finding more than that would require genealogical information and some additional context.<\/p>\n\n\n\n<p>Although with lower accuracy, an autosomal DNA test kit could even help you find a tenth cousin.&nbsp;<\/p>\n\n\n\n<p>Accessing more distant relatives requires more relatives to be tested in order to compare how much DNA is shared within the extended family. For example, if you want to confirm a connection with a 5th cousin, you might need to test 20 or more first and second cousins to see how much they share with a 4th cousin once removed or with a possible 5th cousin.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large is-resized\"><img decoding=\"async\" src=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-5.jpg\" alt=\"Persons looking at a computer\" class=\"wp-image-18463\" width=\"486\" height=\"324\" srcset=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-5.jpg 337w, https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/autosomal-5-300x200.jpg 300w\" sizes=\"(max-width: 486px) 100vw, 486px\" \/><figcaption class=\"wp-element-caption\">DNA testing companies help you find relatives from home. <a href=\"https:\/\/unsplash.com\/@wocintechchat?utm_source=unsplash&amp;utm_medium=referral&amp;utm_content=creditCopyText\">Christina @ wocintechchat.com<\/a>.
