Answer:
The answer to the first question is A.
The answer to the second question is False.
Step-by-step explanation:
An animal's fur color is like a human's skin color. If both parents are the same color, the children will have the same. If it is a mix, it will either mix the colors or just be one. So as both mice are white colored, the offspring will be white furred too.
Now for the second question. Once again, just like humans, mice inherit traits about the same. The traits from the parents will most likely carry on. There is also times where a new trait comes in. This is not very common but it happens occasionally.
