Assume further that normal coat color (N) is dominant (Links to an external site.)Links to an external site. to black (n) and brown eyes (B) are dominant to blue (b). Suppose the alpha male and alpha female of a pack (these are the dominant individuals and assume they do all of the breeding) are black with blue eyes (male) and normal colored with brown eyes (female). The female is also heterozygous (Links to an external site.)Links to an external site. for both traits. Based on Mendelian expected, how many of the 16 offspring living in the pack will have each of the following genotypes?
