The wingless fruit fly phenotype (unable to grow wings) is recessive to normal wing growth. A wingless male fruit fly is crossed with a wingless female fruit fly and 100% of the offspring have normal wings. Which of the following is the most likely explanation for these observations? The wingless fly phenotype does not appear in the offspring because it is lethal. Two different wild-type genes are required to produce normal wing growth and both parents contain mutations in the same gene. None of the other answers are correct. Each parent carries a mutation in a different gene affecting wing formation such that complementation is observed in the offspring. The wingless allele is sex-linked.
