Why are helpful 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 primary benefit of sexual reproduction over asexual reproduction is

• increased probability that some offspring will have traits that help them survive in changing conditions.

• the ability to produce offspring without any genetic disorders.

• the decreased probability that some offspring will have genes that are different from the parent, who is already well adapted to the environment.

• the reproduction of clones that can produce a new genes through mutation.
