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.

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,...

Question 25 2 pts In dragons, the dominant allele R causes solid tail color, and the recessive alleler results in white spots on a colored background. The black coat color allele Bis dominant to the brown allele b, but these genes can only be expressed if the animal has an mm genotype at a third gene locus. Animals that are M are yellow regardless of which allele from the Blocus is present. A mating between a solid yellow-tailed male dragon...

In rabbits normal hair texture is dominant to a greasy, unkempt-looking type of hair called "wuzzy." If a homozygous normal-haired rabbit makes with wuzzy rabbit, determine the relative frequency of each genotype and phenotype that will occur the F1 generation. A. What will be the phenotype resulting from the matting of two individuals from F1 generation? B. What is the phenotype ratio? C. What is the genotype ratio? The long hair of the Persians cat s recessive to the short...
