Extreme heterogeneity in intercourse chromosome differentiation and dosage settlement in livebearers

Importance

Morphologically and chromosomes have actually over and over evolved over the tree of life. Nonetheless, the level of differentiation involving the intercourse chromosomes differs significantly across types. As intercourse chromosomes diverge, the Y chromosome gene task decays, making genes regarding the intercourse chromosomes paid down to just one practical copy in men. Mechanisms have actually developed to pay with this decrease in gene dosage. (more…)
