Biology
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?

Ответ:
Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.
