Age and sex-ratio expression in Drosophila mediopunctata.
The sex-ratio trait--production of progenies with excess of females due to X-linked meiotic drive in parental males--has a variable expression in Drosophila mediopunctata. We tested the effect of male age and found that aging increases the expression of sex-ratio, a fact relevant for the interpretation of field data and for experimental design.
