This test has helped customers discover their genetic genealogy, which would not have been possible without it.&nbsp;<\/p>\n\n\n\n<p>This article covers the essential things you should know about Y DNA and Y chromosome DNA testing genealogy. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-the-y-dna-test\"><strong>What is the Y DNA test?<\/strong><\/h2>\n\n\n\n<p>Y DNA test, otherwise called the <a href=\"https:\/\/nebula.org\/blog\/y-chromosome-test\/\">Y chromosome DNA test<\/a>, is a male-specific genealogical DNA test used for exploring a man\u2019s patrilineal or direct father\u2019s-line ancestry. To better understand the test concept, you first need to know about the Y chromosome.<\/p>\n\n\n\n<p>The Y chromosome makes a genetic distinction between males and females. It is also called a \u201csex chromosome\u201d because it determines whether a child will be biologically male or female.<\/p>\n\n\n\n<p>Males receive one X chromosome from their mother (who has two X chromosomes) and a Y chromosome from their father (who has one X and one Y chromosome). The Y chromosome doesn\u2019t change, except if there&#8217;s an alteration due to a mutation. If there\u2019s no alteration, then the same Y chromosome your great grandfather got from his father will be passed on to your grandfather and your father, and finally to you.<\/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\/ydna-1.png\" alt=\"Y DNA lineage tree\" class=\"wp-image-18220\" style=\"width:325px;height:256px\" width=\"325\" height=\"256\"\/><figcaption class=\"wp-element-caption\">Y-DNA is inherited through the paternal line. <a href=\"https:\/\/commons.wikimedia.org\/wiki\/File:Y-DNA_inheritance.svg\">Wikipedia<\/a>. CC-<a href=\"https:\/\/creativecommons.org\/licenses\/by-sa\/4.0\/deed.en\">Attribution-Share Alike 4.0 International<\/a>.<\/figcaption><\/figure>\n\n\n\n<p>Since there\u2019s little or no alteration in the Y chromosome transfer chain from father to son, the Y DNA test will help males trace their genealogy through their paternal line and learn more about their family history. Although not as definite as a <a href=\"https:\/\/nebula.org\/blog\/paternity-test\/\">paternity test<\/a>, you may be able to use Y DNA test to find a father. It can even go more in-depth to search for your great grandfather or your great-great-grandfather, and so on.<\/p>\n\n\n\n<p>Since the Y DNA test only tests the Y chromosome, it gives no information about the maternal lineage because females don\u2019t bear the Y chromosome. You can learn more about the <a href=\"https:\/\/nebula.org\/blog\/ancestry-y-chromosome-mitochondrial-dna\/\">Y chromosome and mitochondrial DNA<\/a> (genetic information passed from mother to child) on our blog.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-take-a-y-dna-test\"><strong>How to take a Y DNA test<\/strong><\/h2>\n\n\n\n<p>To take a Y DNA test, follow the directions included in the product. Many tests can be performed at-home. The general procedure includes:<\/p>\n\n\n\n<p><strong>Order the test kit online:<\/strong> You can visit the company\u2019s website directly to <a href=\"https:\/\/nebula.org\/blog\/how-to-get-a-dna-test\/\">place your order<\/a>. You can also order from third-party websites such as Amazon as well. You&#8217;ll receive the test kit at the address you provided.<\/p>\n\n\n\n<p><strong>Open the kit and register:<\/strong> Some Y DNA testing companies require that you register the kit on their website before use. During the registration, you may have to submit specific personal information to aid their research.<\/p>\n\n\n\n<p><strong>Collect the sample:<\/strong> Collect the sample as indicated on the kit. Some kits may require a saliva sample; some may need you to scrub your inner cheek walls with a swab. You\u2019ll find which one is required as part of the information on the label.<\/p>\n\n\n\n<p><strong>Mail it back to the company:<\/strong> Label the sample and send it directly to the company where it\u2019ll be analyzed.<\/p>\n\n\n\n<p><strong>Wait for your result:<\/strong> You may have to wait 4-6 weeks for a Short Tandem Repeat (STR) test or longer for a more comprehensive Big Y-700 test. Most companies will send you an email when your result is ready. You can then login into their website and download your result.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-who-can-take-a-y-dna-test\"><strong>Who can take a Y DNA test?<\/strong><\/h2>\n\n\n\n<p>Y DNA test is only designed for males because the Y chromosome is only inherited through the paternal lineage. For instance, you would be unable to trace your maternal grandfather through Y DNA testing since your mother can\u2019t transfer Y DNA. On the other hand, if you are a male and want to trace regarding your grandfather, running a Y chromosome test would be an appropriate choice.<\/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\/ydna-2.jpg\" alt=\"X and Y chromosomes\" class=\"wp-image-18228\" style=\"width:392px;height:361px\" width=\"392\" height=\"361\"\/><figcaption class=\"wp-element-caption\">The X and Y chromosomes.

It can help you to find out more about your long-distant ancestors.<\/p>\n\n\n\n<p>For instance, Y DNA testing allows you to locate common ancestors using a company\u2019s Y-DNA database. Since the <a href=\"https:\/\/nebula.org\/blog\/what-does-dna-stand-for\/\">DNA<\/a> remains unchanged on the Y chromosome, you can trace your ancestors along their migration routes, giving you more information on the geographical origins where your male ancestors lived and migrated.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-to-find-a-reliable-y-dna-company\"><strong>How to find a reliable Y DNA company<\/strong><\/h2>\n\n\n\n<p>Finding a reliable Y DNA company does not have to be difficult. Consider the following tips when choosing a testing company:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-search-for-y-dna-testing-reviews-online\">Search for Y-DNA testing reviews online<\/h3>\n\n\n\n<p>Go online and search for some of the best test companies. Take the time to read about them, including their reviews. The reviews will educate you about how accurate and useful the test results are and how the company deals with customers. <\/p>\n\n\n\n<p>Some companies have customer reviews on their website while others you can find on third party websites like Amazon or independent review companies like Trustpilot. Such reviews on sites other than the company\u2019s page are often more reliable and remove biases.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-read-their-privacy-policy\">Read their privacy policy<\/h3>\n\n\n\n<p>Reading the privacy reviews of DNA testing companies can help you make the right choice. A company is not reliable if they can\u2019t guarantee your privacy protection with them. Remember that your Y DNA test results contain part of your genetic blueprint and you might not want them to be used by a third-party or compromised by computer hackers. <\/p>\n\n\n\n<p>Hence, it&#8217;s good to read the company\u2019s privacy policy and see whether they have all it takes to protect your information or not. Do they have strong security to protect your information? If yes, then they may be the best choice for you.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-the-y-dna-test-explained\"><strong>The Y DNA test explained<\/strong><\/h2>\n\n\n\n<p>There are hundreds of markers on the <a href=\"https:\/\/nebula.org\/blog\/yseq-review\/\">Y chromosome<\/a>, but the tests generally examine 10-111 short tandem repeat (STR) markers. The marker test looks at segments of DNA on the Y chromosome. It also looks at the SNP marker. To better understand this concept, let\u2019s break down what these terms mean.<\/p>\n\n\n\n<p>A SNP, or single-nucleotide polymorphism, is a change to a single nucleotide in a <a href=\"https:\/\/nebula.org\/blog\/history-of-the-dna-model\/\">DNA sequence<\/a>. The more SNPs two people have in common, the better the chances are that they\u2019re related. The SNP tests also provide information about the haplogroup.&nbsp;<\/p>\n\n\n\n<p>A haplotype, also known as a signature, a DNA signature, or a genetic signature, is a set of markers on a single chromosome, inherited together. Haplogroups are distinct to geographical locations and can help map where your ancestors migrated.&nbsp;<\/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\/ydna-3.png\" alt=\"Y DNA haplogroups\" class=\"wp-image-18236\" style=\"width:482px;height:305px\" width=\"482\" height=\"305\" srcset=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/ydna-3.png 378w, https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/ydna-3-300x190.png 300w\" sizes=\"(max-width: 482px) 100vw, 482px\" \/><figcaption class=\"wp-element-caption\">World Map of Y-Chromosome Haplogroups. <a href=\"https:\/\/commons.wikimedia.org\/wiki\/File:World_Map_of_Y-DNA_Haplogroups.png\">Wikipedia<\/a>. CC-<a href=\"https:\/\/creativecommons.org\/licenses\/by-sa\/3.0\/deed.en\">Attribution-Share Alike 3.0 Unported<\/a>.<\/figcaption><\/figure>\n\n\n\n<p>A haplotype is the numbered results of a genealogical test. There are haplotypes with a low frequency of occurrence and ones with a high frequency of occurrence. The ones with a high frequency of occurrence are called common, while the former is called uncommon. The haplotype will help determine under which category your DNA sample falls, whether it is common or uncommon.<\/p>\n\n\n\n<p>Marker, or STRs, are the series of repeating nucleotides that are usually tested for in basic Y-DNA tests. Matching STRs in a Y DNA test indicate a genetic relationship between two males.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-interpreting-the-test-results\"><strong>Interpreting the test results<\/strong><\/h2>\n\n\n\n<p>The test requires comparing the 12 marker results of one individual to the 12 markers of another individual with the same surname. If the result matches 12\/12, there is a 99% probability that the two are related within the time-frame indicated in the MRCA tables.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-large\"><img decoding=\"async\" width=\"624\" height=\"187\" src=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/ydna-4.png\" alt=\"Example of Y DNA test results\" class=\"wp-image-18244\" srcset=\"https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/ydna-4.png 624w, https:\/\/nebula.org\/blog\/wp-content\/uploads\/2021\/03\/ydna-4-300x90.png 300w\" sizes=\"(max-width: 624px) 100vw, 624px\" \/><figcaption class=\"wp-element-caption\">Y DNA test results. <a href=\"https:\/\/www.youtube.com\/watch?v=ekB9LY_aL04\">FTDNA YouTube<\/a>.&nbsp;<br><\/figcaption><\/figure>\n\n\n\n<p>On the other hand, if the match is 11\/12, there\u2019s still a high probability that they\u2019re related, provided that the 11\/12 <a href=\"https:\/\/nebula.org\/blog\/dna-match\/\">DNA matches<\/a> are within the same surname.<\/p>\n\n\n\n<p>If you compare the 25 markers of one individual with that of another individual, and you get a 25\/25 result, then there\u2019s a 99% probability that the individuals are related at a much closer time frame than the 12 markers.<\/p>\n\n\n\n<p>If you compare the 12 marker results of an individual with another surname but the scores match, then they are most likely not recently related. Recently related means a time frame of about 1000 years or 40 generations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-nebula-genomics\"><strong>Nebula Genomics<\/strong><\/h2>\n\n\n\n<p><a href=\"https:\/\/nebula.org\/whole-genome-sequencing-dna-test\/\">Nebula Genomics<\/a> provides a more accurate result than most common DNA tests you may know.
