Evolution

In an experiment using quantitative genetic approaches to investigate the evolution of butterfly eye-spots as a model system for understanding development. There are 3 groups of butterfly populations: small (mean diameter = 2.6 mm), intermediate (3.4 mm), and large eyespots (3.9 mm). Each group comprises 1/3 of the population. The heritability of eyespot diameter in this population is 0.17. 1)What is the expected size (give a number value in mm) of the eyespots in the next generation if:

a) Only the group with the small eyespots is allowed to reproduce
b) Only the intermediate eyespots
c) Small and large eyespot are mixed together and allowed to reproduce

2) For each group, why might eyespots in the next generation not equal to what you might expect?
