Homework Answers
Answer - that the genes for fur pattern (spotted vs. non-spotted) and fur color are on the same chromosomes.
Above process is a dihybrid cross. If both the trait are present in different chromosome means it undergo independent assortment and gives a ratio of 9:3:3:1.
If both the trait are present in same chromosome they not give the same ratio but they give the all four possibility offspring.

In cocker spaniels, solid coat color is dominant over spotted coat color. If two heterozygous solid dogs were crossed to each other, what would be the probability of having a first litter of five pups, the firstborn with solid fur, and then among the next four, three with solid fur and one with spotted fur; and then a second litter of seven pups in which the firstborn is spotted and the remaining six are solid animals. Please give the answer...

A dog's coat color and pattern is determined by many genes, including the two autosomal genes S and A. S (solid) is dominant to s (spotted), and A (black) is dominant to a (tan). A female with a solid tan coat is mated with male having a solid black coat. The puppies are 2 solid tan, 2 solid black, 1 spotted tan, 1 spotted black. What are the most likely genotypes of the parents? (assume the genes are on different...

Fur color in dogs can be black, brown or white. The B gene is responsible for fur color. Dogs that inherit a dominant B will have black fur. Dogs that inherit 2 recessive alleles, bb, will have brown color. There is a second gene that contributes to fur color in dogs: gene I. Individuals who inherit a dominant allele, I, at this location, will always have white color. Individuals who inherit the homozygous recessive condition, ii, will be able to...

In Labrador retrievers, black coat color (B) is dominant to brown (b). Suppose that a black Lab is mated with a brown one and the offspring are 4 black puppies and 1 brown. What can you conclude about the genotype of the black parent?

In wolves, gray coat color (G) is dominant to black (g) and brown eyes (B) are dominant to blue (b). The genes that control these traits are located on different chromosomes. The alpha male of the pack has the dominant phenotype for both traits and is heterozygous for both traits. The alpha female has brown eyes and a black coat; she is heterozygous for eye color. Which option represents gametes that would be made by the alpha female? B. b,...

In rabbits, the English type of coat which is white-spotted (W) and is dominant over the Non-English, unspotted (w) coat while short hair (S) is dominant over long Angora hair (s). When homozygous English, Angoras were crossed with non-English short-haired rabbits, and the F1 dihybrids were test crossed, the following offspring were obtained: 12 English and short-haired rabbits; 10 non-English Angoras; 75 English Angoras and 60 non-English short-haired rabbits. Show progeny phenotype, genotype and totals for each (2pt), calculate the...
