A population of 100 crayfishes were observed in the wild. Three colors exist in this population; 47 red (RR), 13 orange (RY), and 40 yellow (YY).

A. Calculate the observed total number of each allele in the population (1 point) and the observed allele frequencies (1 points).

B. Using the Hardy-Weinberg equilibrium equation (p2 +2pq+q2=1.0) calculate what the predicted genotype frequencies would be if under Hardy-Weinberg equilibrium (2 points) and calculate the predicted number individuals of each genotype (2 points).

C. How do the observed genotypes of the population differ from the predicted genotypes (2 points)?

D. What conclusions can you make based on the differences you see in your observed population (2 points)?

    In the figure, p is the frequency of allele A, and is the frequency of allele a in a diploid population. Assuming no differences in fitness, pand should also be the frequencies of A gametes and a gametes produced by the adults. The A and a gametes combine during fertilization to produce diploid zygotes. If mating is random and the population is large, the proportion of offspring with each of three genotypes (AA, Aa, and aa) can be predicted using...

  • A mutation in one of the hemoglobin genes causes sickle cell anemia. The sickle cell allele,...

    A mutation in one of the hemoglobin genes causes sickle cell anemia. The sickle cell allele, S, severely reduces fitness in people who are homozygotes, SS. In contrast, people with at least one normal hemoglobin allele, A, do not suffer the effects of sickle cell anemia, even if the individual is a heterozygote, AS. Interestingly, in areas with high rates of malaria, a single Sallele confers some resistance to malarial infection. Suppose there is a population with the observed and...

    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,...

    23. Flies with red eyes are homozygous (RR) for the reddish eye pigment. Flies with orange eyes are heterozygous (Rr), and white-eyed flies are homozygous recessive (rr). ​You have a population with the following frequencies ​36 red eyes + 48 orange + 16 white eyes. ​ i. Determine the allele frequencies for R and r. R = r = ii. What are the phenotypic frequencies predicted by Hardy-Weinberg? iii. Is this population at Hardy-Weinberg equilibrium?

    A population of flour beetles has 1000 individuals. Normally the beetles are red in color; however, this population has a utation in the gene for body color that results in black beetles that are designated by the rr genotype. Red body color is dominant to black so the genotypes RR and Rr result in red beetles. Assume the population is in Hardy-Weinberg equilibrium, with a 50% frequency of each allele for body color. A) --- what is the frequency of...
