FrY recovery from wildtype and mutant males (38° 1 hr. heat shock at 0–24 hours of development).

Males were testcrossed individually to y w females. FR = fragment ratio calculated as FrY/(FrY + Y) sons; SR = sex ratio calculated as (total male progeny)/(total female progeny); N, total males testcrossed; % fertile is fraction of testcrossed males that produced any progeny.
