Question details

l) You decide that Ecology is the field for you and apply to the Onconta State MS in Biology program. Your major professor works on the predatory habits of snow leopards. In some species, the degree of tail kinkiness (from straight to bent to kinked) is determined by dosage of a functional allel animals of each type in a single litter. The mother had a bent tail, while the father had a fully-kinked tail. At the end of the field season, you have collected the following data: A) What are the likely genotypes of the two parents? auses kinking. While you are helping your advisor out in the field, you keep track of numbers of Kinked tail bent tail 6 Straight tail 6 B) Based on your answer to A, do you think there was an extra-pair copulation (the female mated with a second male)? Why or why not? (2pts) 2) You have type A blood. Your partner has type B blood. After generation of biological offspring, you have 2 children with type B blood, and one with type A blood. What are the likely genotypes of you, your partner, and your offspring? (2 pts) 3) A test-cross is used to determine the genotype of an individual with a functional phenotype. An organism with a functional phenotype (but unknown genotype) is mated to a homozygous individual with a non-functional phenotype and the progeny are examined. If a red- flower producing plant is test-crossed to a homozygous white-flower producing plant, what would the phenotypic ratios be if: A) The red flowers were RR B) The red flowers were Rr? (1pt) 4) A color-blind male human has children with a female that can see colors. What would the expected phenotype ratios be if: A) The female was homozygous B) The female was heterozygous (1 pt) 5) A metallic blue-colored Indian blue peahen with long pinion feathers is crossed with a dull brown-colored Indian blue peacock with short pinion feathers. Half of the resulting peacocks are metallic blue with short pinions and half the resulting peacocks are metallic blue with long pinions. Half of the resulting peahens are dull brown with short pinions and half the peahens are dull brown with long pinions. Long pinions are the result of a functional protein. A) Which gene is sex-linked? B) What are the genotypes of each parent and each type of offspring? (3 pts) 6) A long winged male crow with a head ruff mates with a short winged crow without a head ruff All of their male offspring have long wings, half of them have a head ruff and half lack a head ruff. All of the female offspring have long wings and half have a head ruff and half do not. A) Are either of these genes sex-linked? B) What is your reasoning? C) What is the most likely genotype for each parent and type of offspring? (4 pts) 7) A homozygous white-flowered plant is crossed with a homozygous dark purple-flowered plant. All of the seeds grow into pale purple-flowered plants. A) If there is no dosage effect, is it more appropriate to write the genotype for the white-flowered plant Ww or pp? B) What is your reasoning? (3 pts) 7) You cross a RrBb male with an rrBb female. If they had 64 children, how many would you expect to be rrBb (2 pts) 8) If a couple has 5 children, what is the probability that they will all be girls? (1pt) 9) Hunchback serves as a silencer protein for the gene encoding Ultrabithorax. B) How do you know? (1pt) A) Which of these two genes is epistatic to the other?

Just need some help with this genetics homework assignment, some of it makes sense to me. Any help would be wonderful, thank you!
