Summary
I discuss a number of experiments designed to explore the genetic basis of sexual ornamentation and associated life history traits in guppies. This system is unusual because of the large Y-linked contribution to ornamentation and male fitness, and because the Y-chromosome is implicated in inbreeding depression. I discuss the implications of intralocus sexual conflict for the evolution of sex-linkage in guppies and the potential for such a process to drive the evolutionary erosion of Y-chromosomes.
