In a population of Drosophila melanogaster reared in thelaboratory, the mean wing length is 0.55 mm and therange is 0.35 to 0.65. A geneticist selects a female withwings that are 0.42 mm in length and mates her with amale that has wings that are 0.56 mm in length.a. What is the expected wing length of their offspringif wing length has a narrow-sense heritability of 1.0?b. What is the expected wing length of their offspring ifwing length has a narrow-sense heritability of 0.0?
