A classic dataset on wing coloration in the scarlet tiger moth (Paneaxia dominula) shows that coloration in this species is from a single-locus, two-allele system with incomplete dominance. Data for 1715 tiger moths is given: White-spotted WW 1535 Intermediate spots Ww 168 Little spotting ww 12 What are the wing coloration allele frequencies of the scarlet tiger moth? What are the genotypic frequencies?
This is a classic data set on wing coloration in the scarlet tiger moth (Panaxia dominula).

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.
The type of plumage found in mallard ducks is determined by three alleles at a single locus: MR, which encodes restricted plumage; M, which encodes mallard plumage; and md which encodes dusky plumage. The restricted phenotype is dominant over mallard and dusky; mallard is dominant over dusky (MR>M>md). If a duck with the restricted phenotype mates with a mallard type and their offspring ratios are 2 restricted, 4 mallard and 4 dusky, then what is genotype of the parents? O MR M x M md O MR MR x M md O MR md x M md O MR md x M M O Impossible to determine from information provided

Tatuo Aida investigated the genetic basis of color variation in the medaka (Aplocheilus latipes), a small fish found in Japan (T. Aida. 1921. Genetics 6:554–573). Aida found that genes at two loci (B, b and R, r) determine the color of the fish: fish with a dominant allele at both loci (B_ R_) are brown, fish with a dominant allele at the B locus only(B_ rr) are blue, fish with a dominant allele at the R locus only (bb R_) are red, and fish with recessive alleles at both loci (bb rr) are white. Aida crossed a homozygous brown fish with a homozygous white fish. He then backcrossed the F1 with the homozygous white parent and obtained 228 brown fish, 230 blue fish, 237 red fish, and 222 white fish. Q.What results would you expect for a cross between a homozygous red fish and a white fish?

Among a population of lizards inhabiting an arid habitat, the skin color is controlled by two alleles—B (brown skin color) that is dominant over b (green skin color). The green lizards comprise only 4 percent of the population whereas the brown lizards comprise the rest. Over a long period of time, increased rainfall in the area leads to transformation of the habitat, with growth of shrubs and small trees. The brown and green lizard numbers almost reverse with the green lizards approaching 81 percent of the total population. Calculate the allele frequency for the green skin color before and after the climate change occurred. Why did the brown lizard, which initially had greater relative fitness than the green lizard, reduce in number drastically? A. 2, 9; because relative fitness is dependent on environmental conditions B. 0.2, 0.9; because relative fitness is dependent on environmental conditions C. 0.2, 0.9; because the green lizard population acquired new…
