Dogs such as Goldendoodles are the result of....

• Artificial Selection 
• Natural Selection

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

• Because those individuals are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the organism knew it needed that trait, survives, and passes it on.
