Natural selection

A grizzly bear survives because he is well-adapted to his environment. When he reproduces he passes on those traits to his offspring. this process is called

• Natural Selection

• Selective Breeding

• Random mutations

• Variations in a species

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.

Modern whales developed their traits through natural selection.  What occurs during the process of natural selection?

• Organisms choose mates from other species to create new species
• Breeders selectively cross organisms with desired traits
• Only the fittest organisms can survive and reproduce
• Organisms remain exactly the same over time.
