This is a classic data set on wing coloration in the scarlet tiger moth (Panaxia dominula). Coloration in this species had been previously shown to behave as a single-locus, two-allele system with incomplete dominance. Data for 1612 individuals are given below: White-spotted (AA) =1469 Intermediate (Aa) = 138 Little spotting (aa) =5 Calculate the following frequencies: A=, a=, AA=, Aa=, aa=
Butterflies show 3 phenotypes due to incomplete dominance at the D locus with alleles DY and DB giving green phenotype in heterozygotes and yellow and blue in homozygotes. a) A population of butterflies showed 49% yellow, and 51% blue and green. What percentage of the gametes for the next generation would contain the DB allele? b) In another population only 1% of the butterflies are blue, what is the DY allele frequency? c) If the butterflies were subject to predation by birds that could easily detect blue & yellow individuals what effect would you expect this to have on the genotype and allele frequencies over time? Indicate possible percentages.

In domestic cats, the allele for short hair (L) is dominant and the allele for long hair (I) is recessive. You are studying a population of cats found on Iwato Island and have determined that the frequency of the recessive long hair allele is q = 0.3. A) What is the frequency of the dominant allele for short hair? p = B) What is the predicted percentage of cats who have heterozygous genotypes? • C) What predicted percentage of cats on this island will have long hair phenotypes? • D) Describe one condition that could change the allele frequencies (the values of p and q) in a population.
8% of XY individuals are color blind in a population. Assume Hardy-Weinberg conditions. Submit your answer as it is. a) What is the percentage of color-blind XX individuals? b) What is the percentage of XX individuals who are carriers? c) If this population has 1000 individuals with 50% of male and 50% of female, how many carriers are present in this population? Submit your answer as it is. Do not round up.
Lizard scale coloration has a complete dominance relationship where green scales are dominant to blue scales. There are 1536 green individuals, and 64 blue individuals. Calculate: A) the frequency of the dominant alleles (round to the nearest tenth) B) the frequency of the recessive alleles (round to the nearest tenth) c) the frequency of individuals with the dominant genotype (round to the nearest hundredth) d) the frequency of individuals with the heterozygous genotype (round to the nearest hundredth) e) the frequency of individuals with the recessive genotype (round to the nearest hundredth)
A total of 1000 members of a Central American population are typed for the ABO blood group. In the sample, 421 have blood type A, 168 have blood type B, 336 have blood type O, and 75 have blood type AB. Part A Use this information to determine the frequency of ABO blood group alleles in the sample. Recall that when considering genes with three alleles whose frequencies are represented by the variables p, q, and r, the sum of genotype frequencies resulting from trinomial expansion is: (p+q+r)² =p² + 2pq+q2+2pr+r²+2gr = 1
Orange coat color in cats is due to an X-linked allele (XO) that iscodominant with the allele for black (X+). When genotypes at the orangelocus were determined for a sample of cats in Minneapolis and St. Paul,Minnesota, the following data were obtained:XOXO females 11XOX+ females 70X+X+ females 94XOY males 36X+Y males 112Calculate the frequencies of the XO and X+ alleles for this population.
In a randomly mating laboratory population of Drosophila, 4 percent of the flies have black bodies (encodedby the autosomal recessive b), and 96 percent havebrown bodies (the wild type, encoded by B). If this population is assumed to be in Hardy–Weinberg equilibrium, what are the allele frequencies of B and b and thegenotypic frequencies of B/B and B/b?
For the fish model organism Medaka (Aplocheilus latipes), genes at 2 loci (B, b and R, r) determine color of the fish. Fish that have the dominant allele at both loci (B_ R_) are brown, fish with a dominant allele at the B locus (B_ rr) are blue, fish with a dominant allele at the R locus only (bb R_) are red, and fish that are homozygous recessive at both loci (bb rr) are white. What is the expected phenotypic ratio of offspring of cross between a homozygous brown and homozygous white Medaka fish? What is the expected phenotypic ratio of offspring if you then generate an F2 generations from the progeny above? Assume that you performed the cross and you observed 465 brown fish, 142 blue fish, 165 red fish, and 61 white fish in the F2 generation. Use a chi-square test to compare the observed and expected numbers of offspring. What conclusions can you draw from your statistical analysis of these results?
An autosomal locus has alleles A and a. We are given the frequency of individuals with the autosomal recessive phenotype. Which of the following statements is TRUE? Choose all that are true. Note: HWE = Hardy-Weinberg equilibrium a) If we assume HWE, we can calculate both allele frequencies b) If we assume HWE, we can calculate the genotype frequencies that we weren't given c) We can calculate both allele frequencies even if we don't assume HWE d) We can calculate q = Freq(a) even if we don't assume HWE e) Even if we don't assume HWE, we can calculate the genotype frequencies that we weren't given
