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)?

The following genotypes were observed in a population: Genotype: JJ (40), Jj (45), jj (50) a. Calculate the observed genotypic and allelic frequencies for this population. b. Calculate the expected numbers of individuals for each genotype if this population were in Hardy- Weinberg equilibrium. c. Using a chi-square test, determine whether the population is in Hardy-Weinberg equilibrium.

Assume you have a population of stinkbug larvae scored for their genotypes at the PGI-2 allozyme locus: PGI-2a/PGI-2a: 125 individuals PGI-2a/PGI-2b: 250 individuals PGI-2b/PGI-2b: 125 individuals Now assume that only 70% of the heterozygotes survive to adulthood and become stinkbugs. a) Calculate the observed genotype and allele frequencies for the initial larvae. b) Calculate the expected Hardy-Weinberg genotypic frequencies for the larvae. Are the larvae in Hardy-Weinberg equilibrium? c) What are the genotypic and allele frequencies among adults in the...

For a population with allele frequencies of f(M) = .2 and f(N) = .8, what are the EXPECTED genotypes under Hardy-Weinberg Equilibrium for the MN blood group? (hint: use the Hardy-Weinberg formula: p2 + 2pq + q2 = 1)

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 sample of 2,000 individuals from a human population was scored for MN blood group. The following genotypes were found: 1,600 MM 250 MN 150 NN Calculate the observed genotype frequencies and expected genotype frequencies under Hardy–Weinberg equilibrium to fill in the blanks to the following questions. Remember to put a zero in front of the decimal point (e.g. 0.47) and round to the significant digits suggested. The observed genotype frequencies (use to 3 significant digits) are: MM = MN...

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,...

A wildflower native to California, the dwarf lupin (Lupinus nanus) normally bears blue flowers but occasionally bears pink flowers. Flower color is controlled by a single diploid locus, with the blue allele (B) completely dominant over the pink allele (b). In a wild population of lupins, there are 100 pink lupins and 2291 blue lupins, for a total of 2391. 1) Calculate the genotype and allele frequencies of this population, assuming that the population is in Hardy-Weinberg equilibrium. Show the...
