A young entomologist is trying to increase body hairs in Drosophila. His original population has a mean of 7.5 hairs, and he selects flies with a mean of 10 hairs to inter-mate and produce his next generation. The mean number of hairs in the resulting population was 9.
1. What is the narrow-sense heritability (h2) for number of body hairs in this Drosophila population (show your work)?
2. What would have been the mean number of body hairs in the next population if she had selected individuals with a mean of 8.5 hairs?
3. If she wanted a mean of 10 hairs in the progeny, what should have been the mean number of hairs in the individuals selected as parents?
