Question

n mice, black fur (B) is dominant to white (b) . At different locus, a dominant allele (A) produces a band of yellow just below the tip of each hair in mice that have black fur, which gives a frosted appearance that is termed agouti. Expression of the recessive (a) allele results in a solid coat color. If double heterozygous agouti parents are crossed, what color will most of the offspring be ?

Answer 1

Black fur with solid coat

Step-by-step explanation:

Given -

Black fur allele is represented by "B"

and white fur allele sis represented by "b"

Yellow band allele is represented by "A" and

solid coat color allele is represented by "a"

Genotype of double heterozygous agouti parents will be

"BbAa"

Crossing BbAa we get -

BA Ba bA ba

BA BBAA BBAa BbAA BbAa

Ba BBAa BBaa BbAa Bbaa

bA BbAA BbAa bbAA bbAa

ba BbAa Bbaa aaAa bbaa

Most of the offsrping will be Black fur with solid coat
