Question

The average thorax length in a Drosophila population is 1.01 mm.
You want to practice selective breeding to make larger Drosophila. To
do so, you choose 10 parents (5 males and 5 females) of the following
sizes: 0.97, 0.99, 1.05, 1.06, 1.03, 1.21, 1.22, 1.17, 1.19, 1.20. You
mate them and then determine the thorax lengths of 30 offspring (half
male and half female): 0.99, 1.15, 1.20, 1.33, 1.07, 1.11, 1.21, 0.94,
1.07, 1.11, 1.20, 1.01, 1.02, 1.05, 1.21, 1.22, 1.03, 0.99, 1.20, 1.10,
0.91, 0.94, 1.13, 1.14, 1.20, 0.89, 1.10, 1.04, 1.01, 1.26. Calculate the
realized heritability of thorax length in this group of flies.
