Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.
• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

A mutation causes a new fur color variation to appear in a mouse population. In which of the situations described below would the new fur color become more common than the old color in the mouse population?

• A. If plenty of food is available in the mouse habitat.

• A. If the new fur color gene is a recessive allele.

• If the amount of reproduction in the mouse population stays the same.

• A. If the new fur color gene is helpful in the survival of mice and their offspring.
