dd-ons Help в I U A Calibri 12 三三1 |:三 6. Consider a guinea pig with a homozygous genotype and a white fur color phenotype. a. What is the probability this parent will produce a gamete with the dominant allele? b. What is the probability this parent will produce a gamete with the recessive allele? C. If 31 sperm cells are collected from this guinea pig, how many would you expect to have the recessive allele (as determined by sequencing the gene)? !!!
A wild-type fruit fly (heterozygous for gray body color andred eyes) is mated with a black fruit fly with purple eyes. Theoffspring are wild-type, 721; black purple, 751; gray purple, 49;black red, 45. What is the recombination frequency betweenthese genes for body color and eye color? Using informationfrom problem 3, what fruit flies (genotypes and phenotypes)would you mate to determine the order of the body color, wingsize, and eye color genes on the chromosome?

17. Three recessive traits in aardwolf (a real animal) are stripe-less (s), dwarf (d), and fluffy mane (f). A stripe-less and fluffy female aardwolf mates with a dwarf male aardwolf to produce an F1 that is all WT (has stripes, normal size, and non-fluffy mane). When an F1 is test crossed to a fully recessive aardwolf, the following F2 are produced: Stripe-less, fluffy, normal sized 89 Striped, non-fluffy, dwarf 92 Stripe-less, non-fluffy, dwarf 1 Striped, fluffy, normal sized 2 11 13 19 20

. As we learned in this chapter, the white mutation ofDrosophila studied by Thomas Hunt Morgan isX-linked and recessive to wild type. When truebreeding white-eyed males carrying this mutationwere crossed with true-breeding purple-eyed females,all the F1 progeny had wild-type (red) eyes. When theF1 progeny were intercrossed, the F2 progeny emergedin the ratio 3/8 wild-type females: 1/4 white-eyedmales: 3/16 wild-type males: 1/8 purple-eyed females:1/16 purple-eyed males.a. Formulate a hypothesis to explain the inheritanceof these eye colors.b. Predict the F1 and F2 progeny if the parental crosswas reversed (that is, if the parental cross wasbetween true-breeding white-eyed females andtrue-breeding purple-eyed males).

When homozygous yellow mutant rats [J] are crossed with homozygous black mutant rats [N], all F1 is grey [G]. In F2, we obtain 10 [J], 28 [G], 8 [N] and 2 light individuals. Tick the plausible explanation(s): O O O the allele responsible for the grey colour is dominant over the alleles responsible for the black and yellow colour no genetic interaction here, the 2 genes act independently no genetic interaction here, it is a monohybridism with one allelic series no correct answer the allele responsible for the yellow colour is epistatic on the gene responsible for the black colour the allele responsible for the black colour is epistatic on the gene responsible for the grey colour
