Extreme heterogeneity in intercourse chromosome differentiation and dosage settlement in livebearers

Extreme heterogeneity in intercourse chromosome differentiation and dosage settlement in livebearers

Importance

Morphologically and chromosomes have actually over repeatedly developed over the tree of life. But, the level of differentiation between your intercourse chromosomes differs significantly across types. 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 with this lowering of gene dosage. Right right right Here, we execute a comparative analysis of intercourse chromosome systems across poeciliid species and discover variation that is extreme their education of intercourse chromosome differentiation and Y chromosome degeneration. Also, we find proof for the full situation of chromosome-wide dosage compensation in seafood.
