The Hardy-Weinberg model makes the following assumptions: no selection at the gene in question; no genetic drift; no gene flow; no mutation; random mating.
What are the five assumptions of the Hardy-Weinberg equilibrium quizlet?

What are the assumptions for Hardy-Weinberg equilibrium check all that apply?
The assumptions of the Hardy-Weinberg equilibrium equations are: 1) the population is very large, 2) the population is closed, meaning that there are no individuals immigrating into or emigrating out of the population, 3) there are no mutations occurring on the gene in question, 4) individuals within the population are …
Which of the following is not an assumption of Hardy-Weinberg genetic equilibrium?
Which of the following is not an assumption of Hardy-Weinberg equilibrium? * Populations must select non-random mates. * No selection must be taking place. … Individuals cannot change, but genotype frequencies in a population can change.
What are the factors affecting Hardy-Weinberg equilibrium?
-Factors affecting the Hardy-Weinberg equilibrium are:
- Mutations: – These are sudden, large, and inheritable changes in the genetic material can occur in all directions. …
- Recombinations during Sexual Reproduction: …
- Genetic Drift: …
- Gene migration:
What is meant by an allele?
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. … Alleles contribute to the organism’s phenotype, which is the outward appearance of the organism. Some alleles are dominant or recessive.
What is the Hardy-Weinberg equilibrium quizlet?
Hardy-Weinberg equilibrium: the condition in which both allele and genotype frequencies in a population remain constant from generation to generation unless specific disturbances occur.
How does evolution occur quizlet?
The process in which organisms change over time and is based off phenotype. When there is a change in the environment and the gene pool causing some to die and some to live. You just studied 11 terms!
How do you know if something is in Hardy-Weinberg equilibrium?
To know if a population is in Hardy-Weinberg Equilibrium scientists have to observe at least two generations. If the allele frequencies are the same for both generations then the population is in Hardy-Weinberg Equilibrium.
Why is the Hardy-Weinberg model useful quizlet?
Why is the Hardy-Weinberg principle useful? The Hardy-Weinberg principle represents an ideal situation that seldom occurs in the natural world. In unrestricted random mating, each individual in a population has an equal chance of mating with any individual of the opposite sex.
