opulation of cats can be either black or white; the black allele (B) has complete dominance over the white allele. Given a population of 1,000 cats, 720 black and 280 white, determine the allele frequency, the frequency of individuals per genotype, and a number of individuals per genotype

Given the following observed genotype frequencies (AA 0.45, Aa 0.16 and aa 0.39) for a gene that determines coat color with incomplete dominance in a population of lemmings.  Allele "A" results in a dark colored coat.  Allele "a" results in a light colored coat.  What percent of the population would possess a dark coat as their phenotype?

In cats, the black allele (B) is dominant over white allele (b). Given a population 2000 cats, 1680 black and 320 white, determine the allele frequency, the frequency of individuals per genotype and number of individuals per genotype.

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. In another population only 1% of the butterflies are blue, What is the DY allele frequency?

The ability to taste the chemical compound PTC (phenylthiocarbamide) is coded for by a single gene with two alleles. Let T stand for the allele that codes for tasting and t for the allele that codes for non-tasting. This allele exhibits complete dominance, such that heterozygotes can also taste PTC. Suppose that out of a population of 100 students, 70 are tasters. Estimate the allele frequencies and the frequencies of TT, Tt and tt genotypes in the population. Show all your work, and clearly state your logic and any assumptions you make in estimating the frequencies
