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.

Some scientists compared fossils of the common ancestor of horses with modern horses. The table shows what the scientists found during their analysis.

The scientists claim that modern horses are better adapted for survival in the present-day environment than the common ancestor would have been. Which statement best support this claim?

• Organisms with four legs will develop a hoof because of the need to balance on four legs.

• Organisms will acquire helpful traits from their surroundings to survive.

• Organisms that have hooves are more likely to reproduce.

• Organisms with multiple toes are easily seen by predators, so parents choose not to pass the trait on to their offspring.
