what is mtdna or y-dna tests?
483368
MtDNA and Y-DNA tests are utilized to identify archeological cultures and migration paths of a person's ancestors along a strict mother's line or a strict father's line. Based on MtDNA and Y-DNA, a person's haplogroup(s) can be identified. Only men can take Y-DNA tests, since women lack a Y chromosome.

The test works by detecting tiny bits of fetal DNA floating through an expectant mom's bloodstream. In particular, the test looks for little fragments of a Y chromosome, which only males have. Some Y chromosome DNA in the blood sample means it's a boy; none means it's a girl.

A common public use for mtDNA in DNA testing is in determining ancestry. Because mtDNA does not change as rapidly as nuclear DNA, and because it is not mixed with the father's (paternal) DNA, it leaves a clearer record of distant ancestry – although only through the mothers' (maternal ancestry).

Screening kits, like the Pink or Blue Early DNA Pregnancy Test, look for the presence of the male Y chromosome in a few drops of blood taken through a finger prick. If it's there, you're having a boy; if not, it's a girl.

Their most powerful genealogy tools, the Y-DNA and mtDNA tests, are also their most expensive. However, if you simply get the cheaper autosomal DNA test, then upload your raw data to GEDmatch, you can get the same or better answers with a lower cost.

An autosomal DNA test is going to tell you roughly what percentage of your DNA comes from Native American ancestors, but it is only an estimate. If you want to be certain that you have Native American ancestors, the mtDNA and YDNA tests are the way to go.

The Y chromosome is one of the two sex chromosomes in humans (the other is the X chromosome). The sex chromosomes form one of the 23 pairs of human chromosomes in each cell. The Y chromosome spans more than 59 million building blocks of DNA (base pairs) and represents almost 2 percent of the total DNA in cells.

Description. Mitochondria are structures within cells that convert the energy from food into a form that cells can use. ... Although most DNA is packaged in chromosomes within the nucleus, mitochondria also have a small amount of their own DNA. This genetic material is known as mitochondrial DNA or mtDNA.

Result processing times: Family Finder results typically take 2 to 4 weeks. mtDNA results typically take 6 to 8 weeks. Y-DNA results typically take 3 to 6 weeks.

But they have some limitations. A drawback with Y-DNA and mtDNA comes from how they are handed down between generations. Since the Y chromosome is passed from father to son, you can only get information about paternal ancestors. ... Mitochondrial DNA is similar because it is passed down from mother to child.

Big Y-700 DNA Test: When To Use It. ... In January 2019, Family Tree DNA released the latest-and-greatest version of its Big Y DNA test: the Big Y-700. As the name suggests, this is a Y-chromosome DNA test, useful for sorting out genealogical relationships on your paternal side (father's father's father's father, etc.).

Nucleus and Mitochondria: Similarities The main difference between nuclear DNA and mitochondrial DNA is simply the amount of it and the specific products produced. Also, the structures have very different jobs. ... To simplify greatly, the nucleus is the brains of the cell operation, while mitochondria are the muscle.

The human mitochondrial DNA (mtDNA) is a double-stranded, circular molecule of 16 569 bp and contains 37 genes coding for two rRNAs, 22 tRNAs and 13 polypeptides. The mtDNA-encoded polypeptides are all subunits of enzyme complexes of the oxidative phosphorylation system.

Both AncestryDNA and 23andMe have a DNA matchmaking service, where you can learn about, and make contact with, genetic relatives. But AncestryDNA has tested the DNA of more than 10 million people, compared to 23andMe's more than 5 million tests.

MyCatDNA is an easy-to-use DNA testing service for cats that helps you see what your cat is carrying in its DNA. Testing can be performed to all cats of all breeds, as well as mixed-breed cats, regardless the age or size of the cat.

Both Ancestry and 23andMe allow you to download your raw DNA. It's important to note that only your autosomal DNA raw data can be transferred to other sites. The YDNA and mtDNA results from 23andMe can't be transferred, since other sites either don't use them or test them differently.
