Elephant seals are a sexually dimorphic species of marine mammal that lives off the coast of California. The females, which weigh around 1000 lbs, are much smaller than the males, which may weigh up to 5000 Ibs. Suppose that scientists measured the weight of three adult female elephant seals and their female offspring. Parent Weight Offspring Weight 920 742 999 780 1014 787 Calculate the narrow sense heritability, h', of weight for female elephant seals to two decimal places. What conclusions can be drawn from these data?

The correlation coefficient for the height data of students at Trent (Offspring~Midparent correlation) is 0.56. What is the heritability of height? If one parent’s height were 2 inches above the population mean and the other’s were 6 inch above, what would be the expected deviation of the height of their child from the population mean.
