2B Mutation and Natural Selection

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 occurs in a particular animal and quickly begins to increase in frequency throughout the population.  Which of the following are you most likely to conclude?

• The mutation makes the animal grow larger
• The mutation does not confer any benefit or harm to the animal
• The mutation makes the animal more susceptible to predators
• The mutation increase the probability that the animal will reproduce.
