You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A survey of 800 trees from several groves indicates that the average shelled almond weight is 5.71 g. You select the 40 trees producing the biggest almonds (average shelled almond weight of 6.48 g), then cross-pollinate the flowers from these trees. You plant the almonds produced by these flowers and when the resulting trees reach maturity, you measure the size of their almonds and find that the average shelled almond weight is 5.85 g.
1. Calculate the selection differential.
2. Calculate the response to selection.
3. Calculate heritability (h2).
4. If you were to carry out this breeding program for multiple generations would you expect to see almond production to be strongly influenced by genetics, environment, or a combination? Explain.
