Humans normally have 46 chromosomes, which come in 23 pairs, as well as some mitochondrial DNA. From the mitochondrial DNA, and 22 of the 23 other chromosome pairs, there is nothing to tell you whether the DNA came from a male or a female. The genetic difference between males and females resides in that last chromosome pair, the sex chromosomes. At the sex chromosomes, women have two X chromosomes, while men have one X chromosome and one Y chromosome. So, if you have a discrete source of your DNA sample, like a hair, you could do a couple of things. You could test it for the presence of Y-chromosome genetic material.
These include mtDNA and the Yline DNA test. The mtDNA, or mitochondrial DNA test, is the type of DNA testing that finds traits that are inherited through the motherâs genes. This type of test is conducted in both male and female. Meanwhile, the Yline DNA testing is a type of test that finds traits passed from the father to the son. In reading the results of mtDNA test, a match means that the two people have a common maternal ancestor. On the other hand, the Yline DNA test helps determine the distance of these two individuals with respect to the common ancestor. How to read DNA test results? In a DNA test report, the DNA markers are provided with chart-type readout.
