Mz. Sukhanova et al., Alkaline phosphatase in Drosophila melanogaster strains differing in male mating activity and their F-1 hybrids, GENETIKA, 34(9), 1998, pp. 1239-1242
The activity of alkaline phosphatase (AP) was studied in adults of highly a
ctive (HA) and low active (LA) Drosophila melanogaster strains and their F-
1 hybrids, both under normal conditions and after a heat shock (38 degrees
C). Under normal conditions, the HA strain expressed a higher AP activity c
ompared to that in the wildtype strain Canton-S and dominated in respect to
this character. The AP activity showed a sexual dimorphism, as it was high
er in females of both strains. Heat shock (38 degrees C) induced no alterat
ions in the AP activity of D. melanogaster.
