Recent studies described … The Y chromosome does not undergo recombination, making it particularly prone to the fixation of deleterious mutations via hitchhiking. This has been proposed as an explanation as to why there are so few functional genes on the Y chromosome. Hitchhiking is necessary for the evolution of higher mutation rates to be favored by natural selection on evolvability.
