NGSS.MS-LS4-4

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.

• Become less likely to eat poison ivy.
• Not change in the proportion of goats that can and can not eat poison ivy.
• Eat all the poison ivy and leave only plants all the goats can eat.
