You are given data for a population. The AA individuals average a phenotype of 150 units, the Aa individuals 130 units and the aa individuals 100 units. You discover that 64% of the individuals are AA, 32% are Aa and 4% are aa. You assume the population has been randomly mating and that differences in phenotype are due solely to the genotypes. What is the effect (or value) of the A allele? 1) 8.8 units 2) 4.4 units 3) -17.6 units.
