In an inbred line of Drosophila melanogaster with marker genes on the sex‐chromosomes as well as on one of the autosomes, it was shown that double fertilization (two sperms fertilizing one egg) is a reality and that gynandromorphic flies can be the result of double fertilization as well as of X‐chromosome loss. In this inbred line it happens with about the same frequency. It was further shown that double fertilization involves fertilization of two different meiotic products from the egg.
