In human population X, consider the simple Mendelian trait for freckles. F is the dominant allele and f is 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 me 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

VERY EASY QUESTION. Below college level.

I will rate and like. Thank you for your work.

In human population X, consider the simple Mendelian trait for freckles. F is the dominant allele
and f is 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 me 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?
