Color in McIver beetles is determined by two alleles at one gene locus. McIver beetles must have a heterzygous genotype (genotype A1A2) in order to have a brown color phenotype. Calculate the frequency of the brown beetles in the population if the frequency of the A1 allele is 0.6.

A given autosomal locus has three possible alleles (A1, A2, and A3). Assuming that the numbers of individuals with the six possible genotypes are as follows, what would be the frequency of the A1 allele in the population?   A1A1 = 30 A1A2  = 27 A2A2 = 12 A1A3 = 17 A2A3   = 10 A3A3 = 4 What would be the frequency of the A1A2 genotype? Assume the population is under Hardy-Weinberg equilibrium.   A. 0.03   B. 0.107   C. 0.27   D. 0.317   E. 0.09   F. 0.182

If a population has an allele A1 frequency of 0.59 and an allele A2 frequency of 0.41, what is the expected frequency of the A2A2 genotype?  Answers have 2 decimal places.

Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. Another flock of geese is determined to have observed and expected numbers of individuals recorded in the table below.    Observed Expected DD 392 303.78 Dd 155 327.15 dd 172 88.08  Determine whether the flock is in Hardy-Weinberg equilibrium by performing a chi-square test. Show all of your work. Use the following table to determine the critical value to which you’ll compare your calculation of the chi-square statistic. Degrees of freedom P = 0.05 1 3.841 2 5.991 3 7.815

Consider an autosomal locus with alleles A and a. If the the allele frequencies are as follows Freq(A) = 0.4, Freq(a) = 0.6. , then what is the predicted frequency of heterozygous Aa individuals, assuming the population is in Hardy-Weinberg equilibrium? Freq(Aa) = ? Enter a number between 0 and 1, inclusive, for example 0.33

For a 2 allele locus, p=0.7.  If the population consists of 100 individuals, how many are homozygous for the q allele?
