Brooks reports in the 6 July Nature that male guppies that are sexually more attractive are also
evolutionarily less fit (Nature 2000, 406:67-70). This may reflect negative pleiotropic effects of genes
for attractiveness, such as the energetic cost of creating large amounts of pigments. Alternatively,
deleterious alleles may be hitching a ride in the region of the Y chromosome that has attractiveness
genes such as those for color patterns. The increased attractiveness of the male fish ensure the
chromosome's genetic survival, but suppression of recombination on the Y chromosome means that the
deleterious alleles are not weeded out.
