Overwhelming heterogeneity inside intercourse chromosome differentiation to dosage payment at livebearers

Importance

Morphologically then functionally distinct X to Y chromosomes posses over and over repeatedly developed over the tree to lives. But their degree to differentiation between your intercourse chromosomes changes considerably around species. The Y chromosome gene activity decays, leaving genes on the sex chromosomes reduced to a single functional copy in males as sex chromosomes diverge. Mechanisms have actually developed to pay because of this decrease in gene dosage. Right Here, people execute a relative research to intercourse chromosome techniques all-around poeciliid types plus find overwhelming variation as part of the amount to intercourse chromosome differentiation to Y chromosome degeneration.
