Single females of the indicated genotypes were mated to two w1118/Y males. Vials were changed and examined on days 5, 10, 15, 20 and 25 as described in materials and methods. Crosses were done at 27°. SD, standard deviation.
a
For average fertility, the difference between the w+ and w classes was tested by a one-tailed t-test. *P < 0.05; **P < 0.01; ***P < 0.001, respectively.
b
N dropped during the course of the experiment due to death of the female and/or male parents.
