Extreme heterogeneity in intercourse chromosome differentiation and dosage payment in livebearers

Importance

Morphologically and chromosomes have actually over and over evolved throughout the tree of life. Nevertheless, the level of differentiation between your intercourse chromosomes differs considerably across types. As sex chromosomes diverge, the Y chromosome gene task decays, making genes regarding the intercourse chromosomes paid off to an individual practical content in men. Mechanisms have actually developed to pay because of this lowering of gene dosage. Right right right Here, we execute a relative analysis of sex chromosome systems across poeciliid species and discover extreme variation in the amount of sex chromosome differentiation and Y chromosome degeneration. Furthermore, we find evidence for a instance of chromosome-wide dosage compensation in fish. Read more
