Males of many species exhibit sperm heteromorphism, in which multiple morphologies of sperm are produced in a common testis (see references in [1]). Polymegaly, a form of sperm heteromorphism, is found in the Drosophila obscura group and is characterized by the production of two size classes of nucleated sperm that differ only in head and tail lengths [1,2]. Both the length and the ratio of sperm types produced is species-specific [1,3-5], and each sperm type develops in its own bundle deriving… CONTINUE READING
