Ychromosomale
YChromosomale, commonly referred to as the Y chromosome, is one of the two sex chromosomes in humans and many other mammals. It determines male development in combination with the X chromosome and is transmitted from father to son, providing a direct record of paternal inheritance. The Y chromosome is comparatively small and gene-dense in important regions, with most of its sequence falling into noncoding and repetitive elements.
It contains the sex-determining region Y (SRY), which initiates male gonadal development by triggering testis formation.
Inheritance of the Y chromosome is strictly paternal; it changes only through mutation. As a result, Y-chromosome
Evolutionarily, the Y chromosome is believed to have originated from an ancestral autosome and has undergone
