Microevolution

Question 1

When a population is in Hardy-Weinberg equilibrium, what is NOT happening to the species?

Answer 1

Evolution

Question 2

Gene flow involves

Answer 2

Individuals moving into and out of the population

Question 3

In the Hardy-Weinberg theorem, p refers to what?

Answer 3

The frequency of the dominant allele

Question 4

In the Hardy-Weinberg theorem, q2 refers to?

Answer 4

The recessive genotype

Question 5

Mutations are important because they bring about

Answer 5

Genetic variation needed for a population to evolve

Question 6

Hardy-Weinberg equation representing the genotype frequencies of a population?

Answer 6

p2 + 2pq + q2 = 1

Question 7

Change in allelic frequencies in a population over generations

Answer 7

Microevolution

Question 8

Natural selection favouring individuals with extreme phenotypes

Answer 8

Disruptive selection

Question 9

Natural selection that favours one phenotypic extreme causing the allele frequency to shift over time in the direction of that phenotype

Answer 9

Directional selection

Question 10

States that when there are no other evolutionary influences, the allele and genotype frequencies in a population will remain constant across generations

Answer 10

Hardy-Weinberg law

Question 11

Describes the condition of an allele or genotype in a population when the frequency remains stable over time

Answer 11

Genetic equilibrium

Question 12

Natural selection for a particular variant (mean) of a characteristic that maintains consistency of a population; occurs in times of environmental stabilitiy

Answer 12

Stabilising selection

Question 13

no selection, no mutation, no migration, large population, random mating

Answer 13

Conditions for genetic equilibrium
