20 Multiple choice questions

Front

What does it mean if a population is in Hardy-Weinberg proportions?

Back

It means that no strong evolutionary forces are acting on the population.

Front

What could explain a deviation from Hardy-Weinberg proportions?

Back

Genetic drift, selection, mutation, or inbreeding.

Front

What is the term for the size of an ideal population that will result in the same amount of genetic drift as in the actual population?

Back

Effective Population size (Ne).

Front

What does Nc represent in population genetics?

Back

Nc represents the headcount of individuals in a population.

Front

What is the difference between census size (Nc) and effective population size (Ne)?

Back

Nc is the headcount of individuals, while Ne is the number of individuals effectively contributing genetically.

Front

What are the two primary effects of genetic drift?

Back

Loss of genetic variation and fixation of alleles.

Front

What is genetic drift?

Back

A mechanism of evolution that refers to random changes in allele frequencies in a population.

Front

What is the significance of effective population size (Ne)?

Back

It helps in understanding the genetic diversity and evolutionary potential of a population.

Front

What factors can lead to a decrease in effective population size (Ne)?

Back

Fluctuating population size, variance in reproductive success, and unequal sex ratios.

Front

What is the formula for calculating Hardy-Weinberg proportions?

Back
