select one:

c. drastic changes to an environment
d. differences with a population of the same species

question 2

- the allele for a widow's peak is dominant over the allele for a hairline with no peak. it is an example of

- the relative frequency of an allele is the allele occurs in a gene pool, compared with the number of times other alleles for the same gene occur. relative frequency is often expressed as a percentage.

- height in humans is one example of

- a gene pool consist of all genes, including all the different alleles, that are present in a population.

answers for those for are
multigenic trait
polygenic trait
single gene trait
bigenic trait
relative frequency
gene pool
