Which type of natural selection leads to an increase in genetic diversity as the population splits into two distinct groups?

• Directional Selection

What is genetic drift?

• Random changes in allele frequency due to chance events

• Favoring extreme phenotypes over the intermediate phenotype

• Selection of the intermediate phenotype

• Movement of alleles between populations

What is bottleneck drift?

• Random changes in allele frequency due to chance events

• Favoring extreme phenotypes over the intermediate phenotype

• Sudden reduction in population leading to loss of genetic diversity

• Introduction of new genetic variations through migration

What is the founder effect?

• Random changes in allele frequency due to chance events

• Favoring extreme phenotypes over the intermediate phenotype

• Sudden reduction in population leading to loss of genetic diversity

• Limited gene pool of a new population

What is genetic equilibrium?

• Random changes in allele frequency due to chance events

• Ideal state where allele frequencies remain constant

What does the Hardy-Weinberg principle describe?

• Random changes in allele frequency due to chance events

• Ideal state where allele frequencies remain constant

What is sexual selection?

• Random changes in allele frequency due to chance events

• Favoring extreme phenotypes over the intermediate phenotype

• Preference for certain characteristics in individuals of the opposite sex

• Movement of alleles between populations

What is gene flow?

• Random changes in allele frequency due to chance events

• Favoring extreme phenotypes over the intermediate phenotype

• Selection of the intermediate phenotype
