What are 5 conditions that must be present in order for the Hardy Weinberg principles to make accurate predictions?

There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene’s allele frequencies may change).

What are the 5 conditions that must be present in order for the Hardy-Weinberg principles to make accurate predictions which of these conditions are never truly met?

Correct answer:

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.

What are the five conditions for Hardy Weinberg equilibrium quizlet?

Terms in this set (5)

  • No mutations. The gene pool is modified if mutations alter alleles or if entire genes are deleted or duplicated. …
  • Random mating. …
  • No natural selection. …
  • Extremely large population size (no genetic drift) …
  • No gene flow (emigration, immigration, transfer of pollen, etc)

What conditions are necessary for a population to be at 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.

What does P mean in Hardy-Weinberg?

The Hardy-Weinberg equation is a mathematical equation that can be used to calculate the genetic variation of a population at equilibrium. … where p is the frequency of the “A” allele and q is the frequency of the “a” allele in the population.

Is migration a gene flow?

Gene flow is also called gene migration. Gene flow is the transfer of genetic material from one population to another. Gene flow can take place between two populations of the same species through migration, and is mediated by reproduction and vertical gene transfer from parent to offspring.

Why is random mating important to Hardy-Weinberg?

If allele frequencies differ between the sexes, it takes two generations of random mating to attain Hardy-Weinberg equilibrium. Sex-linked loci require multiple generations to attain equilibrium because one sex has two copies of the gene and the other sex has only one.

What do PQ p2 2pq and q2 represent?

p2 +2pq + q2 = 1 Where p2 represents the frequency of the homozygous dominant genotype, q2 represents the frequency of the recessive genotype and 2pq is the frequency of the heterozygous genotype.

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 conditions are needed for a population to be in Hardy-Weinberg equilibrium quizlet?

Terms in this set (5)

  • The population is very large.
  • The population is isolated (no migration of individuals, or alleles, into or out of the population).
  • Mutations do not later the gene pool.
  • Mating is random.
  • All individuals are equal in reproductive success (no natural selection).

What are three main causes of evolutionary change?

There are two general classes of evolutionary change: microevolution and macroevolution. Microevolutionary processes are changes in allele frequencies in a population over time. Three main mechanisms cause allele frequency change: natural selection, genetic drift, and gene flow.
