Which situation would most likely result in evolution? question 2 options: an alligator has no alleles for scales. a large population loses a few individuals. a single individual joins a large population. a predator prefers one phenotype to another.

In a relatively small iguana population the allelic frequency is tracked for three generations. webbing is a recessive allele; no webbing is the dominant allele. during one very rainy spring and summer, a flood washes all the iguana without webbed feet out to sea. by the fall, and three generations later, you have the gene pool seen here.

If scientists are wrong about earth's age based on radioactive material and the decay rates are really much faster, how would nuclear power plants be affected?
