Sexual maturation in Drosophila melanogaster females and hybridization with D. simulans males: a study of inheritance modes.

The inheritance mode of Drosophila melanogaster female sexual maturation speed and hybridization with D. simulans males was measured in F1 females from crosses between isofemale lines of D. melanogaster chosen for their high or low hybridization and maturation speed values. The results suggest dominant inheritance for rapid female maturation and intermediate inheritance for hybridization. We discuss results in relation to the evolutionary role of these characters.
