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

• Because they come from dominant alleles.
• Because they come from recessive alleles.
• Because the trait is an acquired phenotype.

What is artificial selection?

• The death of every member of a species

• A change in the structure or amount of the genetic material of an of an organism

• The human practice of breeding animals or plants that have certain desired traits

• The process which individuals that are better adapted to their environment and they survive and reproduce better than less adapted
