When you decide to breed your Labrador retriever Molly and sell the puppies, you discover that two of Mollys four siblings have developed a hip disorder that is traceable to the action of a single recessive allele. Molly herself shows no sign of the disorder. If you breed Molly to a male Labrador that does not carry the recessive allele, can you assure a purchaser that the puppies will also be free of the condition? Explain your answer.
In horses, the coat color black is dominant (B) over chestnut (b). The trotting gait is dominant (T) over the pacing gait (t). A heterozygous black pacer is mated to a homozygous chestnut, heterozygous trotter. a. What are the genotypes of the parents: _____________ and _______________ b. Fill-in the Punnett square
In some cats, the gene for tail length shows incomplete dominance. When a cat with a long tail is bred to a cat with no tail, the resulting offspring have short tails. For each of the following, predict the types of offspring that would result: a) A long tail cat bred to a cat with no tail b) A long tail cat bred to a short tail cat c) Two short tail cats
In sheep, coat color is influenced by two genes. Gene A influences pigment production, while gene B produces black or brown pigment. If two heterozygous white sheep resulted in 12 white sheep, 3 black sheep, and 1 brown sheep, which genotype(s) of the white sheep explain this data? A) The white sheep could be A-B- or aaB-. B) The white sheep could be A_B_ or aabb. C) The white sheep could be A_B_ or A_bb. D) The white sheep must all be aabb. E) The white sheep must all be A_B_.
Both of Ruth's parents have a round face, a dominant trait. Ruth, however, was born with a square face. What does Ruth's phenotype imply about her parents' genes? a. Ruth's parents are both heterozygous when it comes to their facial shape. b. When it comes to facial shape, Ruth's parents gave her one dominant gene and one recessive gene. c. Ruth's parents are both homozygous when it comes to their facial shape. d. Ruth's sister also has a square face.
Which of the following is false? a. the pollen grain shape was studied by Mendel. b. Mendel believed that the characteristics of pea plants were determined by the inheritance units or factors from both parents. c. An allele is one of several possible forms of a gene. d. When the genotype consists of a dominant and recessive allele, the phenotype will be like the dominant allele.
Predict the phenotype corresponding to each offspring genotype if: Gene A is governed by complete dominance and gene B by incomplete dominance. Possible phenotypes for gene A are tall (dominant phenotype) and short (recessive phenotype), and for gene B are red, pink, and white.
In cattle, coat color is controlled by a sex-influenced gene that controls spot coloration. Mahogany and white spots are recessive in bulls, where as red-and-white spots is dominant in cows .A mahogany and white spotted cow is crossed with a red-and white spotted bull. The cow gives birth to a single calf with red-and-white spots. a. What are the genotypes of the cow, the bull, and the calf? Use H for dominant and h for recessive. Cow Bull Calf b. The red calf is eventually crossed with a heterozygous male. What is the probability that the first 3 calves will be mahogany with white spots? c. What is the probability that the cross in “b” will result in the first 3 calves being males with mahogany and white spots and the 4th calf a female with red and white spots?
An organism that is heterozygous for a recessive and dominant allele will display what phenotype? A) Something completely different from the dominant and recessive phenotypes B) Recessive C) A mixture of the dominant and recessive phenotypes D) Dominant E) A dysfunctional phenotype
An Agouti with Himalayan gene female rabbit was mated by an albino male. The phenotypes for the filial generation are... a. Agouti and Himalaya b. Agouti, Himalaya and Albino c. Agouti and Albino d. Himalaya and Albino
In cats, the allele for black fur (B) is dominant over the allele for brown fur (b). A heterozygous female cat mated with a homozygous recessive male cat.a. What is the genotype of the female cat?b. What is the phenotype of the female cat?e. Draw a Punnett square to show what kinds of kittens these two cats could make. What fraction of the kittens would you expect to have each genotype?
Please use instructions from above Red roan hair colour in some horses is due to codominance of the white allele and the red allele. If a red roan horse mates with a white horse, indicate the genotypic and phenotypic ratios that would result.
