<p><b>New page</b></p><div>'''Y chromosome''' is one of the two [[sex chromosomes]] in mammals, including humans, and many other animals. The other is the [[X chromosome]]. Y chromosome is the sex-determining chromosome in many species, since it carries the genes responsible for male development.<br />
<br />
== Characteristics ==<br />
<br />
The Y chromosome is one of the smallest human chromosomes. It represents about 2% of the total DNA in cells. Despite its small size, the Y chromosome has a crucial role in the body. It carries the [[gene]]s that determine male sex. These genes are involved in the development of male [[gonads]], the production of [[sperm]], and the development of male secondary sexual characteristics at [[puberty]].<br />
<br />
== Genetic content ==<br />
<br />
The Y chromosome contains about 200 genes. The most important of these is the [[SRY gene]], which initiates the process of male sex determination. Other genes on the Y chromosome are involved in [[spermatogenesis]], the process by which sperm are produced.<br />
<br />
== Evolution ==<br />
<br />
The Y chromosome has a unique mode of [[evolution]]. Unlike other chromosomes, which undergo [[recombination]], the Y chromosome is passed on almost unchanged from father to son. This makes the Y chromosome a useful tool in [[genetic genealogy]], the study of ancestry and family history using DNA.<br />
<br />
== Y chromosome in genetic genealogy ==<br />
<br />
In genetic genealogy, the Y chromosome is used to trace paternal lineage. This is possible because the Y chromosome is passed down almost unchanged from father to son. Changes, or [[mutation]]s, in the Y chromosome can be used to trace the history of a male lineage.<br />
