Evolution of the Degenerated Y-Chromosome of the Swamp Guppy, Micropoecilia picta

25 Mar 2022

Abstract excerpt

The conspicuous colour sexual dimorphism of guppies has made them paradigmatic study objects for sex-linked traits and sex chromosome evolution. Both the X- and Y-chromosomes of the common guppy (Poecilia reticulata) are genetically active and homomorphic, with a large homologous part and a small sex specific region. This feature is considered to emulate the initial stage of sex chromosome evolution. A similar...
