Reinforcement of Gametic Isolation in Drosophila
Figure 4
Selective advantages of enhanced gametic isolation.
(A) Propensity of D. yakuba females to remate with a conspecific in a second, no-choice mating 4 d after an initial mating to a heterospecific male. Grey: sympatric females; white: allopatric females. (B) Mean (SE) number of eggs per D. yakuba female (from either sympatric or allopatric lines) sired by first (heterospecific, white) and second (conspecific, grey) male.
