摘要
Sex differences in physiology and longevity are widely observed. A study that manipulates heterochromatin content in Drosophila Y chromosomes shows no association between the length of the Y chromosome and longevity, thus challenging the hypothesis that Y chromosome-derived heterochromatin causes Y chromosome-bearing animals to live shorter lives.
