1. You have been charged with breeding larger Leprechauns for next St. Patrick's Day. You measure the mass of Leprechauns that you have in your breeding population. The current population mean is 400g. You identify the largest Leprechauns and allow them to breed. The average mass of the breeding Leprechauns is 600g. a) Calculate the selection differential for your breeding program. b) One year later (assume Leprechauns have very fast generation intervals and this corresponds to one generation), you measure the mass of the next generation of Leprechauns. The average mass of Leprechauns in this next generation is 460g. What is the response to selection in your exneriment?
