Shared and Species-Specific Patterns of Nascent Y Chromosome Evolution in Two Guppy Species

3 May 2018

Abstract excerpt

Sex chromosomes form once recombination is halted around the sex-determining locus between a homologous pair of chromosomes, resulting in a male-limited Y chromosome. We recently characterized the nascent sex chromosome system in the Trinidadian guppy (Poecilia reticulata). The guppy Y is one of the youngest animal sex chromosomes yet identified, and therefore offers a unique window into the early evolutionary...
