Favorable genes are passed on to offspring

• True

• False

All organisms share the same

• genome

• DNA bases

• genes

• organelles

When an organism migrates to a new population it adds its' genes to the gene pool. This leads to an increase in what?

• natural selection

• fitness

• genetic variation

• mutations

This happens when organisms migrate or move to a different group

• Gene Flow

• Natural Selection

• Survival of the fittest

• Genetic Drift

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.

• The common ancestors of the reptiles probably came from Equador.
• The common ancestor of each species evolved in Peru and came to the islands at the same time.
