1. If you were to cut all the continents out of a map, and place South America and Africa together, they fit like a jigsaw puzzle.

2. The same plant and animal fossils were found on both sides of the Atlantic Ocean and in areas that are now far away from each other.

3. Ice sheets were found in places that have hot temperatures, and this would happen if those places had previously been in cold locations where ice could form like that.

4. There are similar mountain rages in different countries, which is a sign of the change that has occurred.

Answer:

Bright white fur 3/4

Black fur 3/16

brown fur 1/16

Explanation:

From the Punnet's square analysis (see the attached image);

A_B_ 9/16
A_bb 3/16
aaB_ 3/16
aabb 1/16

A_B_ and A_bb will always give offsprings with bright white fur since allele A always mask the effect of B.

aaB_ will always give offsprings with black fur since allele a does not produce any protein.

aabb will give offsprings with brown fur since b codes for brown fur colour.

Hence, the phenotypic ratio of the offspring will be;

Bright white fur 3/4

Black fur 3/16

brown fur 1/16
