Which of the following is a characteristic of a population at Hardy-Weinberg equilibrium?
When a population is in Hardy-Weinberg equilibrium for a gene, it is not evolving, and allele frequencies will stay the same across generations. There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection.
Which of the following is a requirement for a population to be in Hardy-Weinberg equilibrium apex?
The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection.
Which of the following is not a requirement of populations in Hardy-Weinberg equilibrium?
Answer: natural selection not a requirement for Hardy Weinberg equilibrium.
What conditions are necessary for a population to be at equilibrium?
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 does it mean for a population to be 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.
How do you know if a population 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.
Which of these conditions is not among the requirements of the Hardy-Weinberg equilibrium?
Hardy-Weinberg equilibrium requires no immigration or emigration, a large population, random mating, and no spontaneous mutations (all of which are virtually unavoidable in nature). Natural selection would violate these conditions.
What is the difference between directional and disruptive selection?
In directional selection, a population’s genetic variance shifts toward a new phenotype when exposed to environmental changes. … In diversifying or disruptive selection, average or intermediate phenotypes are often less fit than either extreme phenotype and are unlikely to feature prominently in a population.
Which does not affect Hardy-Weinberg equilibrium?
The Hardy-Weinberg Law states: In a large, random-mating population that is not affected by the evolutionary processes of mutation, migration, or selection, both the allele frequencies and the genotype frequencies are constant from generation to generation. …
Why is population not in Hardy-Weinberg equilibrium?
If the allele frequencies after one round of random mating change at all from the original frequencies, the population is not in Hardy-Weinberg equilibrium and evolution has occurred within the population.
Which of the following is not an assumption of the Hardy-Weinberg equilibrium group of answer choices?
Non-random mating is not an assumption of the Hardy-Weinberg equilibrium, in fact, in order to make predictions about the next generation, random mating must be assumed. Additionally, no new mutations, no gene flow, no genetic drift, and no natural selection must also occur.
