A)SsGg and Ssgg B)SsGg only C)SsGg, ssgg, ssGg, Ssgg D)ssGg and ssgg onlyIn humans, the allele for red-green color blindness is X-linked and recessive. An XY man with normal color vision marries a color-blind XX woman who gives birth to a XX color-blind daughter. A] What is the phenotype and genotype ratios possible for a child born to this couple.

- Holstein dairy cows normally have black-and-white coats. Sometimes, calves with a recessive red-and-white coat are born. A dairy farmer bought a prize-winning black-and-white Holstein bull (male) and mated it to one of his black-and-white cows. To his dismay, the cow produced a red-and-white calf (baby). a)Provide correct notation for the dominant and recessive alleles? b)What is the genotype of the bull? c) What would the phenotyples of the offspring be if the above bull was mated to a red-and-white cow?Brown Enamel of the teeth is a well-known sex-linked dominant trait. Showing ALL work using punnett squares, determine the genotypes of offspring for the following matings: A.) The father of a family has a defect, but the mother does not and does not carry it. B.) The father has the defect, and the mother is heterozygous for it. C.) The father does not have the defect and the mother is homozygous for it. D.) The father does not have the defect and the mother is heterozygous.Given these parents-note, they are NOT quite the same as each other!: mom = Aa Bb Cc Dd dad = Aa Bb cc Dd NOTE that the A gene acts incompletely dominantly. a) What chance does their baby having the "strongest phenotype" in A, being recessive in b, recessive in c, and dominant in D? Give one fraction. Show work. b) phenotype? Now assume mom was CC instead of Cc. Now what is the chance of having that same
- You cross a true-breeding yellow-bodied, smooth-winged female fly with a true-breeding red-bodied, crinkle-winged male. The red body phenotype is dominant to the yellow body phenotype and smooth wings are dominant to crinkled wings. Use B or b for body color alleles, and W or w for wing surface alleles.(4 points) a) What are the genotypes of the P generation flies? b) What will be the genotype(s) and phenotype(s) of the F1 offspring? c) You discover that the genes for body color and wing surface are linked. You perform a dihybrid test cross between the F1 flies from part (b) with a true-breeding yellow-bodied, crinkle-winged fly. Use the following results of this cross to determine the recombination frequency (%) between the body color and wing surface genes. (Remember that the recombinants are the ones that do not resemble the parental types from the P generation.) Body Color Wing Surface # of Individuals red smooth 102 yellow smooth 404 red crinkled 396 yellow crinkled…For Dalmatian dogs, the spotted condition is dominant over non-spotted. (a) Using a Punnett square, show the results of a cross between two heterozygous parents.

- 3) Short tail length in cattle is caused by an X-linked recessive allele. Roan coat colour of cattle is due to co-dominance (other coat colours are red and white). a) Show the results of a cross between a bull which has a roan coat and a short tail and a white cow which is heterozygous long tail. b) What percentage of male calves will have a red coat and a short tail?In cats, long hair is recessive to short hair. A short-haired male is mated to a long-haired female. a) What are all possible genotypes of these two cats? b) What alleles will the gametes of each of these cats contain in their chromosomes?c) What will the kittens from all possible crosses between these two cats look like?d) Two cats are mated. One of the parent cats is long-haired. The litter which results contains two short-haired and three long-haired kittens. What length fur does the second parent have, and what is its genotype?Cats also have a locus (gene) for a character called agouti. In cats with agouti fur, pigment is unevenly distributed (see Fig. 1). The agouti allele is dominant to the allele for regular fur. A male cat who long haired and is heterozygous for agouti fur is crossed with a female who has regular, non-agouti fur and is homozygous for short fur. a) What are the genotypes of these cats? b) What are all of the possible allelic combinations in the gametes from each…The long hair of Persian cats is recessive to the short hair of Siamese cats, but the black coat colour of Persians is dominant to the black-and-tan coat of the Siamese. a) If a true-breeding black long-haired Persian is mated with a true-breeding black-and-tan short-haired Siamese, what are the predicted phenotypes of the cats in the F1 generation? b) If two of the F1 generation cats are then mated, what is the chance of obtaining a long-haired black-and-tan cat in the F2 generation?
