WEEK 8 - POPULATION GENETICS

A group of individuals of the same species that live in the same area and interbreeding, producing fertile offspring.

This statement refers to which term?

• Population

• Population genetics

• Gene pool

• Allele frequency

What is a gene pool?

• A swimming pool for chromosomes

• A collection of all the possible alleles in a population.

• A collection of all the possible alleles in a single individual.

• A collection of all the possible species in a population.

According to Hardy-Weinberg law, genetic equilibrium is achieved when ____________________.

• the population size is small

• there is migrating of genes

• there is random mating

• there is mutation

When a gene pool of a population changed, it means ___________________.

• number of organisms in the population changes

• the population is in genetic equilibrium

• the population is undergoing evolution

• organisms in the population is breeding randomly

If there are 50 flowers, 30 red (RR), 15 pink (Rr) and 5 white (r), how many recessive alleles is in the population?

• 5

• 10

• 20

• 25

Calculate the frequency of heterozygous genotype.

• 0.75

• 0.25

• 0.5

• 1

Five assumptions of Hardy- Weinberg Law for genetic equilibrium include all, but...?

• Random mating

• Same species

• No migration

• Large population size

Which statement is NOT TRUE of the Hardy-Weinberg equation?

• 'p' represents the frequency of recessive alleles in a population.

• The sum of allele frequencies is 1.

• The sum of genetic frequency is 1.

• They are no changes in allele frequencies from one to the subsequent generation.

In a Hardy-Weinberg population, the frequency of the 'a' allele is 0.4. Therefore, the frequency of 'A' allele is __________________.

• 0.6

• 0.48

• 0.2

• 0.16

If q² is 0.35, which is the possible value for p² and 2pq?

• p² : 0.65

  2pq : 0.25

• p² : 0.25

  2pq : 0.65

• p² : 0.35

  2pq : 0.30

• p² : 0.35

  2pq : 0.25
