- Consider the following scenario: In a population of 1000
individuals, 490 are homozygous dominant, 420 are heterozygous, and
90 are homozygous recessive. Answer the following questions about
this population.
- How many total alleles does this population have?
- How many dominant alleles does this population have?
- How many recessive alleles does this population have?
- Based on your numbers from part a, calculate the following
frequencies, and give a written description of each (i.e. what does
each number mean in “real world” terms?).
- p2 =
- 2pq =
- q2 =
- q =
- p =
- The next generation of the above population was found to have
1500 individual: 520 homozygous dominant, 615 heterozygotes and 365
homozygous recessive.
- p2 =
- 2pq =
- q2 =
- q =
- p =
- Is this population evolving? Explain how you know this.

The Hardy-Weinberg principle and its equations predict that frequencies of alleles and genotypes remain constant from generation to generation in populations that are not evolving
.1. The Hardy-Weinberg principle and its equations predict that frequencies of alleles and genotypes remain constant from generation to generation in populations that are not evolving. What five conditions does this prediction assume to be true about such a population? a._______ b._______ c._______ d._______ e._______ 2.

Consider a locus of interest that has two alleles: A and a. A diploid individual carrying these alleles can have one of three genotypes: AA, Aa, or aa; a population will consist of some combination of AA, Aa, and aa individuals. The relatively frequency of each of these genotypes makes up the population's structure. Hardy and Weinberg independently figured out that, in the absence of forces that cause evolutionary change, the population structure will 'settle' or default to equilibrium values,...
