What must be true for a population to be in Hardy-Weinberg equilibrium? There must be random mating in the population; there must be an infinite population size; and there must be no evolution occurring (no natural selection, no genetic drift, no migration and no mutation).
What must be true of a population that is in 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 is true about the 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 does it mean if a population is in 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. -A population in Hardy-Weinburg equilibrium is not changing genetically, not evolving.
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.
What is equilibrium population?
A population in which the allelic frequencies of its gene pool do not change through successive generations. An equilibrium can be established by counteracting evolutionary forces (e.g., a balance between selection and mutation pressures) or by the absence of evolutionary forces. See Hardy-Weinberg law.
What information does Hardy-Weinberg provide about populations that are in equilibrium check all that apply?
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.
How does Hardy-Weinberg expression explain that genetic equilibrium is maintained in a population?
The Hardy–Weinberg principle states that after one generation of random mating genotype frequencies will be p2, 2pq, and q2. In the absence of other evolutionary forces (such as natural selection), genotype frequencies are expected to remain constant and the population is said to be at Hardy–Weinberg equilibrium.
Which statement is a reason that modern human populations never reach Hardy-Weinberg equilibrium?
Which statement is a reason that modern human populations never reach Hardy-Weinberg equilibrium? Evolution rarely occurs in human populations. Mating is random in human populations.
What is true about positive selection for a trait?
What is true about positive selection for a trait? … The frequency of the trait increases. Future generations of offspring of parents with the trait are more likely to survive.
Why is Hardy-Weinberg equilibrium important quizlet?
What is the significance of Hardy-Weinberg equilibrium? The significance of Hardy-Weinberg equilibrium is that there in no evolution and no change in allele frequency. Populations in nature do not meet the conditions of Hardy-Weinberg equilibrium, as all biological populations evolve.
What is the purpose of the Hardy-Weinberg equilibrium?
Hardy-Weinberg Equilibrium (HWE) is used to estimate the number of homozygous and heterozygous variant carriers based on its allele frequency in populations that are not evolving.
What is true of natural selection?
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. … Variation exists within all populations of organisms.
Which of the following is true of evolutionary forces in natural populations?
What is true about evolutionary forces in natural populations? Evolutionary forces can alter allele frequencies in natural populations. Which type of selection acts to eliminate individuals which are intermediate on a phenotypic range? What is the ultimate source of new alleles?
Which of the following is a possible outcome of persistent geographical isolation of two populations?
Which of the following is a possible outcome of persistent geographical isolation of two populations? Allopatric speciation could occur.
