Multiple Choice

The relative frequency of an allele is

• the total number of copies of an allele in a gene pool

• all the genes that are present in a gene pool of a population

• the number of times that the allele occurs in a gene poool, compared to the number of times other allleles for the same gene occur

• the number of times that dominant alleles occur in a gene pool compared with the number of recessive alles

Multiple Choice

A polygenic trait is controlled by

• 2 or more genes

• one gene that has only 2 alleles

• one gene with only one allele

• 2 alleles on 2 genes

Multiple Choice

A group of individuals of the same species that mate and produce offspring is called a

• gene pool

• niche

• genetic family

• population

Multiple Choice

Any change in the genetic material of a cell is called a

• mutation

• single-gene trait

• genotype

• polygenic trait

Multiple Choice

In genetic terms, evolution is defined as any change in the relative frequency of

• a single-trait gene of a population over time

• alleles in the gene pool of a population over time

• genes in a population over time

• phenotypes of a population over time

Fill in the Blanks

all the genes, including all the different alleles for each gene, that are present in a populaiton

Fill in the Blanks

a trait controlled by only one gene

Fill in the Blanks

the particular combination of alleles an organism carries

Fill in the Blanks

all physical, physiological, & behavioral characteristics of an organism

Multiple Choice

What type of cell must a mutation occur in for it to make a difference in evolution?

• Sex Cell

• Body Cell

Fill in the Blanks

The way that organisms swap genes between each other, & can create genetic variation (new strains of drug resistant bacteria)

Multiple Choice

Dominant genes always show up more in the population than recessive.

• true

• false
