Why will genotype frequencies remain at Hardy-Weinberg proportions in a population? -All the genotypes have an equal ability to survive and reproduce. -The recessive allele is never more frequent than the dominant allele. -The heterozygote has the highest likelihood of surviving and reproducing.
Which of these events or conditions is most likely to maintain Hardy-Weinberg equilibrium?
The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection. The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions.
In which condition will the allele frequency of a species remain constant from one generation to the other?
Genetic equilibrium occurs when there is no evolution within the population. In other words, the frequency of alleles (variants of a gene) will be the same from one generation to another. At genetic equilibrium, the gene or allele frequencies are stable—they do not change.
Which condition indicates that the population is most likely in Hardy-Weinberg equilibrium quizlet?
Which condition indicates that the population is most likely in Hardy-Weinberg equilibrium? Mating is random. What is the term for the difference in the physical traits of an individual from those of other individuals in a group?
Under what conditions does the Hardy-Weinberg principle describe the relationship between allele and genotypic frequencies quizlet?
(The Hardy-Weinberg principle describes the relationship between allele and genotypic frequencies when none of the four evolutionary forces is acting. Natural selection, genetic drift, gene flow, and mutation are the four processes that shift allele frequencies in a population.
Which is a characteristic of a population at Hardy-Weinberg equilibrium?
A population of alleles must meet five rules in order to be considered “in equilibrium”: 1) No gene mutations may occur and therefore allele changes do not occur. 2) There must be no migration of individuals either into or out of the population. 3) Random mating must occur, meaning individuals mate by chance.
Which factor does not affect Hardy-Weinberg equilibrium?
According to the Hardy Weinberg law, the allele and genotype frequencies in a population remain constant under absence of factors responsible for evolution. These factors are namely mutation, recombination, gene migration, genetic drift and natural selection.
What is the difference between an allele frequency and a genotypic frequency?
Relative genotype frequency is the percentage of individuals in a population that have a specific genotype. … Relative allele frequency is the percentage of all copies of a certain gene in a population that carry a specific allele. This is an accurate measurement of the amount of genetic variation in a population.
What are the 5 factors that lead to evolution?
Five different forces have influenced human evolution: natural selection, random genetic drift, mutation, population mating structure, and culture. All evolutionary biologists agree on the first three of these forces, although there have been disputes at times about the relative importance of each force.
What does it mean if something is in Hardy-Weinberg equilibrium?
The Hardy-Weinberg equilibrium is a principle stating that the genetic variation in a population will remain constant from one generation to the next in the absence of disturbing factors. … For instance, mutations disrupt the equilibrium of allele frequencies by introducing new alleles into a population.
What happens in a population that is not in Hardy-Weinberg equilibrium quizlet?
A population in Hardy-Weinberg equilibrium is not evolving. If any of these conditions are violated, the population does not stay in Hardy-Weinberg equilibrium, and allele frequencies and genotype frequencies may change from one generation to the next.
