Genetics Test- please help! :) Am I correct?
Homework Answers
Yes absolutely!!
f (A) = f (AA) +1/2 (Aa)
0.5 + 1/2 (0.4)
0.5 + 0.2 = 0.7
or you can use this formula =A2 + 2Aa + a2

The goal of this exercise is to apply population genetics. The frequencies of AA, Aa, and aa genotypes in a chicken population are 0.2, 0.6 and 0.2 respectively. Answer the following questions and show your work supporting your answers: 2.1) [15 points] Provide the genotype and allele frequencies that will be present in the next generation if the previous population is mated to a second population that has for the genotypes AA, Aa, and aa frequencies 0.05, 0.6, and 0.35,...

For a particular gene associated with a degenerative neurological disorder, you surveyed genotype frequencies in a population and found that 16 people had genotype AA, 97 had genotype Aa, 15 had genotype aa. a) Calculate the allele frequencies. b) Calculate the expected genotype frequencies under Hardy-Weinberg Equilibrium. Use the chi-square test to determine whether the observed number of people with different genotypes and expected number of people with different genotypes are significantly different (at an alpha level of 0.05).

4. The Hardy-Weinberg Principle. For a single locus, if the frequency of one allele (allele A) is 0.4, the frequency of the other allele (allele B) is 0.6, what are the expected frequencies of the AA genotype, the AB genotype and the BB genotype in the next generation? What are the eight assumptions that should be met when making the genotype frequency predictions? How do the eight assumptions serve to form a null model for evolution? Finally, how does one...

Here's a hint: Hint 2. How to calculate the
expected frequencies of a different example population Consider an
example population of individuals that have two alleles for a
specific locus, AB and AC. In the population, 70% (0.7) of the
alleles are AB, and 30% (0.3) of the alleles are AC. The expected
frequencies of each genotype can be calculated using the equation
for...

2. Which of the following correctly describes how inbreeding will affect genotype and allele frequencies in Hardy-Weinberg populations? Genotype and allele frequencies will be unaffected. The frequency of heterozygotes will decrease, but allele frequencies will be unaffected. The frequency of homozygotes will increase, and deleterious alleles will decrease. Beneficial alleles will increase in frequency, as well as the genotypes containing those alleles. Genotype frequencies will return to H-W expectations after 1 generation of random mating. 3. Consider a population with...
