Question

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?

O B. b, and g
O Bg and bg
O Bb and 38
O BG. Bg. 6G, bg
O None of these

Answer 1

The alpha female wolf, being heterozygous for eye color and having a black coat, would produce two types of gametes: bG and bg.

Step-by-step explanation:

The question refers to the inheritance of two traits in wolves, with gray coat color being dominant to black, and brown eyes dominant to blue. Given that the genes are on different chromosomes, we can use a simple Punnett square to predict the gametes produced by the alpha female wolf. The alpha female has a black coat and brown eyes with heterozygosity for the eye color (genotype bG), which means her possible gametes can only be either "b" (for the black coat) or "G" (for the brown eyes), since she can only have one allele for each trait in a single gamete.

Therefore, when considering the specific question about which gametes the alpha female wolf would make, the correct answer is she would produce two types of gametes: bG and bg. This is because she can pass on her allele for brown eyes (G) along with the allele for a black coat (b) or her brown eyes allele (G) with the allele for the black coat (b).
