Which of the following is a mechanism of evolution?

Natural selection

Photosynthesis

Mitosis

Osmosis

What is meant by genetic variation?

The presence of different alleles in a population

The number of individuals in a population

The number of generations in a population

The proportion of individuals with a particular genotype in a population

What does genetic drift refer to in population genetics?

The movement of individuals between populations

The random fluctuation of allele frequencies in a population

The deliberate manipulation of genes in a laboratory setting

The process of natural selection acting on a population

What is a gene flow?

The transfer of genes between populations

The process of mutation

The elimination of individuals from a population

The process of artificial selection

Which of the following is an example of a genetic bottleneck?

A sudden decrease in population size due to a natural disaster

A gradual increase in population size due to immigration

A constant population size over time

A population with diverse genetic variations

What is meant by the term 'allele frequency'?

The proportion of individuals with a particular genotype in a population

The number of alleles in a population

The total number of individuals in a population

The number of generations in a population

What role does mutation play in evolution?

Introduces new genetic variation into populations

Stabilizes allele frequencies

Decreases genetic diversity

Reduces adaptation

What is the founder effect?

A type of genetic drift where a small group establishes a new population

The introduction of foreign genes into a population

The process of natural selection in founder species

The formation of new species in isolated environments

What is the Hardy-Weinberg equilibrium?

A state where allele frequencies in a population remain constant over generations

A type of genetic drift

A process of genetic mutation

A mechanism of natural selection

#10

What is directional selection?

A form of natural selection where extreme phenotypes are favored over intermediate phenotypes

A type of genetic drift

A process of genetic mutation

A mechanism of artificial selection

#11

What is the effect of genetic drift on small populations?

Genetic drift has a minimal effect on small populations

Genetic drift increases genetic diversity in small populations

Genetic drift can lead to significant changes in allele frequencies

Genetic drift decreases mutation rates in small populations

#12

What is the difference between gene flow and genetic drift?

Gene flow involves the movement of individuals between populations, while genetic drift refers to random changes in allele frequencies

Gene flow leads to a decrease in genetic diversity, while genetic drift increases genetic diversity

Gene flow occurs only in large populations, while genetic drift occurs only in small populations

Gene flow and genetic drift are synonymous terms in population genetics
