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.
Many genes are unique to the Y chromosome, but genes in areas known as pseudoautosomal regions are present on both sex chromosomes. As a result, men and women each have two functional copies of these genes. Many genes in the pseudoautosomal regions are essential for normal development.
PS:The above content is from google ,I am not getting any words or ideas for the last few alphabets so the last few post’s will be like this only.
PS:I am not a doctor, these are just my findings, my experiences and my infertility warrior friends experiences,which are a part of my life. I am half doctor myself because we go though so much,sometimes I feel I know my diagnosis better than my RE(Reproductive Endocrinologist). Hope these posts make some sense for people who are not a part of this journey.This post is a part of #AtoZchallenge2018.
