The average life span (ALS) was analyzed in flies of the Drosophila melanogaster inbred stock selected for high embryonic mortality (HEM). In is shown that selection resulted in the reduced ALS of HEM stock, as compared with the initial outbred Leric stock. Two equal peaks of mortality were observed in the hybrid females. The peaks mean values usually corresponded to ALS of the parents. A major peak of mortality was detected in hybrid males, and its mean was higher than ALS values characteristic of both parents. The existence of genes controlling "early" and "late" death in D. melanogaster ontogenesis is proposed.
