Evolution Of Populations

Question 1

All populations are…

Answer 1

Not the same

Question 2

What is a gene pool?

Answer 2

Consist of all copies of each allele at every locus in all members of the population

Question 3

What is a heterozygous gene?

Answer 3

Two different alleles at a given locus

Question 4

What is a homozygous gene?

Answer 4

Two identical alleles at a locus

Question 5

What is gene variability?

Answer 5

Genetic variation at the whole gene level

Question 6

Average percentage of loci…

Answer 6

That are heterozygous

Question 7

If there is only one allele at a particular locus in a population that allele is said to be…

Answer 7

Fixed

Question 8

What is the HardyWeinberg equation and equilibrium?

Answer 8

A quantitive way to examine whether a population is evolving or not

Question 9

Why is the Hardy- Weinberg equation?

Answer 9

Assess whether selection or other factors are causing evolution at a locus
Determine what the genetic makeup of a population would be if it were not evolving
Compare that with that data observed for the population

Question 10

Population is not…

Answer 10

Changing or evolving

Question 11

For the Hardy-Weinberg equilibrium to occur…

Answer 11

There must be no mutations, random mating, no natural selection, extremely large population size, and no gene flow
