In chickens, the absence of barred feathers is due to a recessive allele. A barred rooster was mated with a non- barred hen, and all the offspring were barred. These F1 chickens were intercrossed to produce F2 progeny, among which all the males were barred; half the females were barred and half were nonbarred. Are these results consistent with the hypothesis that the gene for barred feathers is located on one of the sex chromosomes?

. In chickens, silver and gold feathering is determined by a single pair of alleles as is slow and rapid feather development. True-breeding males that were silver, slow feathered were crossed with true-breeding females that were gold, fast feathered. All F1 were silver, slow feathered. The F2 phenotypes were as follows: 300 male progeny were silver, slow feathered; 120 females were silver, slow feathered; 123 females were gold, rapid feathered 35 females were silver, rapid feathered; and 32 females were...

In Drosophila, cut wings are controlled by a recessive sex-linked allele (ct), and fuzzy body is controlled by a recessive autosomal allele ( fy). When a fuzzy female is mated with a cut male, all the members of the F1 generation are wild-type. What are the proportions of F2 phenotypes, by sex?

Please answer all the questions, they're related The autosomal recessive allele bw, for brown eyes in Drosophila interacts with the X-linked recessive allele, v, for vermilion eyes, since flies that are recessive for both genes have white eyes. Wild type flies have red eyes. What eye color phenotypes, in what proportions, would be expected in the progeny from a cross of a white-eyed female and a brown eyed male?  Choose the best answer. Select one: a. all females with brown eyes,...

Please show all work step by step!! Please don't just give me answers.Thank you. In whales, the gene controlling tail shape exists as a dominant notched (T) or a recessive smooth (t) allelic form. A separate gene controls whether there are white markings on the dorsal fin or not. The dominant allele of the second gene (W) results in no white markings whereas the other allele (w) results in white markings in individuals homozygous for the recessive allele. The T...

(5 pts) Genes D and E are located in the Drosophila genome. DE·DE females are crossed with de·de males to produce F1 flies that are heterozygous for both traits. What gametes do each of these parents make? F1 females were crossed with de·de males, and 2000 flies were examined. What gametes do each of these parents make? What are the possible genotypes of the offspring produced from the cross in part B? If the genes were sorting independently (not linked),...
