1. In a particular bird species, the tips of the feathers are tinged with blue, white, or silver. The BB genotype calls for blue-tipped feathers. The WW genotype calls for white-tipped feathers. The BW genotype calls for an intermediate with silver-tipped feathers. A mating occurs between a blue-tipped bird and a white-tipped bird. What types of offspring would be expected? Give the genotypes and phenotypes of the possible offspring and the probability of each. 2. The bird species described in question 5 has an ornamental plumage on its head. The plumage feathers are either flexible or stiff. The allele for flexible plumage is dominant over the allele for stiff plumage. A male who is heterozygous for plumage and has silver-tipped wings mates with a female who has stiff plumage with silver-tipped wings. What types of offspring would be expected from this cross? Give the probability of each. 3. In some cats, the gene for tail length shows incomplete dominance. When a cat with a…
1. Suppose you are studying a trait due to three genes that all additively affect the same trait. The genes are A, B, and C. Capital letters symbolize the "phenotype-adding" allele and lower case letters symbolize the "non-adding" allele. (In other words, the behavior of the genes is like those affecting wheat kernel color in the Nilsson-Ehle experiment presented in class). If AaBbCc is testcrossed to aabbcc, how many different phenotypes will be produced in the progeny?
1. Two loci found in mice are suspected to be linked. To test this hypothesis, a group of graduate students performed a test cross between mice that are true breeding for both dominant traits and mice that are true breeding for both recessive traits. Individuals from the F1 generation were crossed with individuals that express both recessive traits. The phenotypic results are shown in the table below. Use chi-square analysis to determine if the graduate students’ hypothesis is supported by the evidence. Phenotype Number of OffspringDominant 1, Recessive 2 132Dominant 1, Dominant 2 128Recessive 1, Recessive 2 118Recessive 1, Dominant 2 124 a. What are the degrees of freedom and the critical chi-square value (from the table)?b. What is the calculated chi-square value?c. Do the results support that the loci are linked or that they are independently assorted (unlinked)?

1. The ability to taste the compound PTC is controlled by a dominant allele T, while individuals homozygous for the recessive allele (t) cannot taste PTC. In a population consisting of 500 individuals, 347 are tasters and 153 are non-PTC tasters. Calculate the frequency of the T and t alleles in this population, and frequency of the genotypes.(Please train yourself to use the Hardy-Weinberg equation.)To present your answers, follow the format in the picture below.
