Question 1

Population

Answer 1

Localized group of individuals capable of interbreeding and producing fertile offspring

Question 2

Microevolution

Answer 2

Change in allele frequencies in a population over generations.

Question 3

Alleles

Answer 3

Alternative forms of the same gene or same genetic locus.

Question 4

Genetic Loci

Answer 4

Specific location of a gene or DNA sequence or position on a chromosome.

Question 5

Genetic Variation

Answer 5

Result of the difference in nucleotide sequences among individuals of a population.

Question 6

Gene Pool

Answer 6

Set of all genes in any population, usually of a particular species.

Question 7

Variation

Answer 7

Can be discrete of quantitative( continuous)

Question 8

Discrete Variation- Polymorphisms

Answer 8

occurrence of different forms among the members of a population.
Two or more clearly different phenotypes exist in the same population.

Question 9

Quantitative Characters

Answer 9

AKA continuous variation.
Like weight and height.
Trait can be the result of multiple genes or genetic loci.

Question 10

Average heterozygosity

Answer 10

Can measure the variation in genes.
Compare all the loci on one chromosome vs. another.
Only works for diploids. No one does this anymore.

Question 11

Nucleotide Variability

Answer 11

Can measure the variation in nucleotide sequence AKA Sequence identity.
Compare DNA sequence between individuals in a population.

Question 12

Cline

Answer 12

A slope pr a gradual and continuous change.
