For each of the following relationships, correlation coefficient for height were determined for 15 pairs of individuals. Father-son: 0.41 Sister-sister: 0.40 Sister-sister (Fraternal twins): 0.39 Sister-sister (identical twins): 0.80 What is the average heritability for height in this group?

An individual carries a somatic mutation that changes a glutamic acid codon to a lysine codon [GAA (GIu) > AAA (Lys)]. Prior to acquiring this mutation, the individual had been exposed to EMS, proflavin, 5′-bromouracil, and X-rays. Which of these agents would be the most likely to have caused this somatic mutation?

The average thorax in a Drosophila population is 1.01 mm. You want to practice selective breeding to obtain larger flies. To do so, you choose 10 parents (5 males and 5 females) whose average thorax length is 1.10. You mate them to produce 30 offspring whose average thorax length is 1.08. Calculate the realized heritability of thorax length in this group of flies.
