In mice, agouti fur is a dominant trait resulting in individual hairs having a light band of pigment on an otherwise dark hair shaft. A mouse with agouti fur is shown here, along with a mouse with solid color fur, which is the recessive phenotype (A = agouti; a = solid color).
A separate gene, which is not linked to the agouti gene, can result in either a dominant black pigment or a recessive brown pigment (B = black; b = brown).
A litter of mice from the mating of two agouti black parents includes offspring with the following fur colors:
a) solid color, black
b) solid color, brown (sometimes called chocolate)
c) agouti black
d) agouti brown (sometimes called cinnamon)

The answer is given below

Explanation:

The 2 traits of the agouti fur mice are determined by non linked genes, which assort independently.

For this purpose we will use the multiplication rule to calculate the probability of agouti brown offspring  (A_ bb) from AaBb parents.

The probability of A_ offspring is 3/4 and the probability of offspring bb is 1/4.

The total probability will be 3/4 x 1/4 = 3/16.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

layer 3 is younger than layer 6.
