AP Bio Insta-Review Topic 7.5: Hardy-Weinberg Equilibrium

What is the effect of nonrandom mating on allele frequencies?

• Nonrandom mating has no effect on allele frequencies.

• Nonrandom mating can lead to changes in allele frequencies and disrupt Hardy-Weinberg Equilibrium.

• Nonrandom mating only affects phenotypic frequencies, not allele frequencies.

• Nonrandom mating increases genetic diversity within a population.

What does 'p' represent in the Hardy-Weinberg equation?

• The frequency of the recessive allele in the population.

• The frequency of the dominant allele in the population.

• The total number of alleles in the population.

• The frequency of heterozygous individuals in the population.

What is genetic drift?

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

• A process that leads to the extinction of species due to environmental changes.

• A method of artificial selection used in agriculture.

• A theory that explains the inheritance of acquired characteristics.

What is the significance of population size in Hardy-Weinberg?

• It determines the color of the organisms.

• It should be large to minimize the effects of genetic drift.

• It affects the mutation rate in the population.

• It has no impact on genetic variation.

What does 'q' represent in the Hardy-Weinberg equation?

• The frequency of the dominant allele in the population.

• The frequency of the recessive allele in the population.

• The total number of alleles in the population.

• The frequency of heterozygous individuals in the population.

What is the importance of the Hardy-Weinberg principle in biology?

• It provides a baseline to measure evolutionary changes in a population.

• It explains the process of natural selection in species.

• It describes the genetic drift in small populations.

• It outlines the stages of cellular respiration.

What is the role of mutations in Hardy-Weinberg Equilibrium?

• Mutations are essential for evolution.

• There should be no mutations occurring in the population.

• Mutations increase genetic diversity.

• Mutations are beneficial for population stability.

What type of mating is required for Hardy-Weinberg Equilibrium?

• Random mating is required, meaning individuals pair by chance.

• Mating based on genetic similarity is required.

• Mating must occur between individuals of different species.

• Mating must be selective and non-random.

What is Hardy-Weinberg Equilibrium?

• A principle that describes the genetic variation in a population that is not evolving, where allele frequencies remain constant from generation to generation.

• A theory that explains how species evolve through natural selection and adaptation.

• A model that predicts the extinction of species due to environmental changes.

• A concept that states that genetic drift has no effect on small populations.

What is a population in biological terms?

• A group of individuals of different species that live in the same area.

• A group of individuals of the same species that live in the same area and interbreed.

• A collection of organisms that are all genetically identical.

• A random assortment of organisms found in a specific habitat.
