EXERCISE 6 HARDY-WEINBERG EQUILIBRIUM In human population X, consider the simple Mendelian trait for freckles. F is the dominant allele and fis the recessive allele. Individuals who are homozygous dominant (FF) or heterozygous (Ff) for the trait express freckles. Individuals who are homozygous recessive (ff) for the trait do not express freckles. In this population, 30% (0.3) of the alleles are recessive (f ) and 70% (0.7) are dominant (F). 1. Use the Hardy-Weinberg equation to determine the genotype frequencies we should expect in the next generation. Be sure to show your work. 2. You have collected data on the observed genotype frequencies of the next generation. They are 60% FF, 30% Ff, and 10% ff. Based on these observations and your expectations, is this trait currently evolving in this population? Why or why not?
