Extreme heterogeneity in intercourse chromosome dosage and differentiation payment in livebearers

Extreme heterogeneity in intercourse chromosome dosage and differentiation payment in livebearers

Importance

Morphologically and chromosomes have actually over and over repeatedly developed over the tree of life. But, the degree of differentiation amongst the sex 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 content in males. Mechanisms have actually developed to pay with this lowering of gene dosage. Right right Here, we execute a comparative analysis of intercourse chromosome systems across poeciliid species and discover variation that is extreme the amount of intercourse chromosome differentiation and Y chromosome degeneration. Furthermore, we find proof for the situation of chromosome-wide dosage compensation in seafood.
