DESCRIPTION:Early work on male colour diversity in guppies found a that a 
 substantial proportion of colour pattern variation is Y-linked\, and this 
 association inspired our current models of sex chromosome evolution. This 
 Y diversity is curious\, given that the loss of recombination between sex 
 chromosomes often depletes Y chromosomes of functional content and genetic
  variation\, which might limit their potential to generate adaptive divers
 ity. We have mapped out Y degeneration and Y haplotype diversity across gu
 ppies and several related species\, and used this in conjunction with deep
  learning image analysis of colouration to determine the role of the Y in 
 male phenotypic variation. Our results indicate a remarkable amount of Y h
 aplotype diversity\, likely maintained by balancing selection related to s
 exual selection.
