In the past Y chromosome was thought to be an empty gene which is now proven not true. It contains fewer genes compared to X chromosomes. Y chromosome are split into two parts pseudoautosomal (PAR) regions sharing the same [[Ancestry|ancestry]] regions on the X chromosome when is recombined in the process of meiosis and the male-specific regions of the Y (MSY) which also has some genes not all share the same [[Ancestry|ancestry]] with the X chromosome.
