even if a well adapted y chromosome manages to maintain genetic activity by avoiding mutation accumulation, there is no guarantee it will be passed down to the next generation. the population size of the y chromosome is inherently limited to 1/4 that of autosomes: diploid organisms contain two copies of autosomal chromosomes while only half the population contains 1 y chromosome. thus, genetic drift is an exceptionally strong force acting upon the y chromosome. through sheer random assortment, an adult male may never pass on his y chromosome if he only has female offspring. thus, although a male may have a well adapted y chromosome free of excessive mutation, it may never make it into the next gene pool. the repeat random loss of well-adapted y chromosomes, coupled with the tendency of the y chromosome to evolve to have more deleterious mutations rather than less for reasons described above, contributes to the species-wide degeneration of y chromosomes through muller's ratchet.
