Farmer John decides to increase the weight of the eggs produced by his chickens.  The average weight of his eggs is 50 grams.  He knows that the heritability of egg weight is 0.5.  He selects for chickens producing eggs that are 64 grams.  The expected average weight of the resulting eggs is:     59     57     54     55     56

Last summer you were walking in the woods when you stumbled upon a group of four tiny baby squirrels. You noticed that they all had different tail lengths. Curious, you decided to measure the tail lengths of the four squirrels. Their tail lengths were found to be: 30 mm, 38 mm, 32 mm, and 28 mm. The heritability for tails in squirrels is 0.33. (This is a fraction, not percent.) What is the variance due to the difference in environment (VE)? Round to two decimals and do not include units.
