Importance
Morphologically and chromosomes have actually over repeatedly developed throughout the tree of life. Nevertheless, the level of differentiation between your 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 an individual practical content in males. Mechanisms have actually developed to pay with this lowering of gene dosage. Right Here, we perform relative analysis of intercourse chromosome systems across poeciliid species and unearth variation that is extreme their education of intercourse chromosome differentiation and Y chromosome degeneration. Also, we find proof for a situation of chromosome-wide dosage compensation in seafood. Continue reading “Extreme heterogeneity in intercourse chromosome differentiation and dosage settlement in livebearers”
