Calculate the frequencies of the genotypes in future generationsif the initial population consists of the following genotypefrequencies:

0.3AA, 0.3Aa, and0.4aa, and meets the requirement of theHardy-Weinberg relationship.

2. What will be the frequency of Aa in the firstgeneration?

3. What is the frequency of aa in the firstgeneration?

For the data set below, determine whether the genotypefrequencies represent a population in Hardy-WeinbergEquilibrium.(The significant digits allow you to assume you canhave an exactly representative sample of 1000 individuals. Thecritical value at probability 0.05 with (only) one degree offreedom is 3.84.) You will use a Chi-squared test and answer thequestions below.

Genotype: AA Aa aa

Frequency: 0.312 0.335 0.353

a. Let p = frequency of the "A" allele and q = the frequency ofthe "a" allele. Within a perfectly representative sample of 1000individuals, how many "A" alleles would there be?

b. Therefore, what is the value of p?

c. After finding the actual values of p and q, what are theexpected values of individuals with the genotypes AA, Aa andaa?

d. What is your Chi-squared value? e. Is this population inHardy-Weinberg equilibrium?

Calculate the frequencies of the AA, Aa, and aa genotypesafter

one generation if the initial population consists of 0.2 AA,0.6

Aa, and 0.2 aa genotypes and meets the requirements of the

Hardy

A particular gene in a given population of individuals has two alleles, A and a. The frequency of the A allele equals the frequency of the a allele. What are the expected genotype frequencies, assuming the population is in Hardy-Weinberg equilibrium?

AA = 0.25, Aa = 0.50, aa = 0.25

AA = 0.5, aa = 0.5
The answer cannot be determined because the allele frequencies are not provided.

A = 0.5, a = 0.5
