Which of the following conditions is not a requirement for Hardy-Weinberg equilibrium?
Explanation: Hardy-Weinberg equilibrium has a set of conditions that must be met in order for the population to have unchanging gene pool frequencies. There must be random mating, no mutation, no migration, no natural selection, and a large sample size. It is not necessary for the population to be at carrying capacity.
What are the 5 assumptions of the Hardy-Weinberg equilibrium?
The Hardy–Weinberg principle relies on a number of assumptions: (1) random mating (i.e, population structure is absent and matings occur in proportion to genotype frequencies), (2) the absence of natural selection, (3) a very large population size (i.e., genetic drift is negligible), (4) no gene flow or migration, (5) …
Which of the following conditions must be met in order for a population to be in Hardy-Weinberg equilibrium quizlet?
The Hardy-Weinberg model states that a population will remain at genetic equilibrium as long as five conditions are met: (1) No change in the DNA sequence, (2) No migration, (3) A very large population size, (4) Random mating, and (5) No natural selection.
What are the 5 evolutionary mechanisms?
There are five key mechanisms that cause a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next. These are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection (previously discussed here).
What are the assumptions of the Hardy Weinberg equilibrium quizlet?
What are the assumptions of Hardy-Weinberg Equilibrium? large populations, no genetic drift, no natural selection/mutation or migration, no assortative mating /sexual selection or inbreeding.
What occurs if at least one of the five conditions of Hardy Weinberg equilibrium are not met?
Do allele and genotype frequencies often change overtime in real populations? Five conditions of Hardy Weinberg equilibrium that cause changes to occur if at least one is not met. … If inbreeding happens, random mixing of gametes does not occur, and genotype frequencies change. 3.
What five conditions must be met for no evolution to occur?
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.
Which of the following must be true in order for a specific allele in a population to remain in a state of equilibrium?
Which of the following must be true in order for a specific allele in a population to remain in a state of equilibrium? Correct Answer(s) : No mutation, natural selection, or gene flow occur in relation to a specific allele.
Which of the following is not a type of natural selection?
Artificial selection is not a type of natural selection, obviously, but it did help Charles Darwin obtain data for his theory of natural selection. Artificial selection mimics natural selection in that certain traits are chosen to be passed down to the next generation.
What are the factors affecting Hardy-Weinberg equilibrium?
The 5 factors are – gene flow, mutation, genetic drift, genetic recombination and natural selection.
How do you do Hardy-Weinberg equilibrium?
The Hardy-Weinberg equation used to determine genotype frequencies is: p2 + 2pq + q2 = 1. Where ‘p2‘ represents the frequency of the homozygous dominant genotype (AA), ‘2pq’ the frequency of the heterozygous genotype (Aa) and ‘q2‘ the frequency of the homozygous recessive genotype (aa).
Which assumption must be met for a population to be in Hardy-Weinberg equilibrium for a specific gene?
The five assumptions of Hardy-Weinberg equilibrium are a large population size, no natural selection, no mutation rate, no genetic drift, and random mating.
