Which of the following statements are true about a gene with two alleles in a population that is in Hardy-Weinberg equilibrium?

Which of the following statements are true about a gene with two alleles in a population that is in Hardy-Weinberg equilibrium? The frequencies of the two alleles may change over time. the frequencies of the two alleles will remain constant over time.

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.

Why do you get different results when you run the same simulation several times Populus?

This is because with a finite population size, there is sampling variation due to genetic drift. This variation results in the fluctuations in the frequency of allele A1 between simulations. Experiment by changing the initial population size (use 10, 100, and 10,000) and running each of these simulations several times.

What are the combined alleles of all the individuals in a population?

The collection of all the genes and the various alternate or allelic forms of those genes within a population is called its gene pool.

Which term indicates that a single gene has two or more alleles present in a population?

A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ.

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.

Which of the following must be true in order for a population to remain in genetic 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 is not a condition that must be met for a population to be at 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.

Why did the pattern vary from run to run?

Why did the pattern vary from run to run? By chance the allele could be established if the individual was able to survive long enough to mate and make offspring. Natural selection acts on very wet populations existing alleles.

Is the change in allele frequencies brought about below species level?

Microevolution is the change in allele frequencies that occurs over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow and genetic drift. Microevolution may lead to speciation, which provides the raw material for macroevolution.

Does gene flow occur at Hardy-Weinberg equilibrium?

At Hardy-Weinberg equilibrium, gene flow must not occur in the population. Gene flow, or gene migration occurs when allele frequencies in a population change as organisms migrate into or out of the population.

Can an individual have two different alleles for one trait?

If an individual inherits two different alleles, they will be heterozygous for the trait. However, a population may have one, two, or many different alleles for a specific gene which could result in one to many different individuals for the trait coded by the gene.

Why does a population have to be large to change allele frequencies?

The population must be large so that no genetic drift (random chance) can cause the allele frequencies to change. No selection can occur so that certain alleles are not selected for, or against.

What is the total number of alleles of a gene?

The total number of all alleles of the gene equals 1000, which is 2 times the number of individuals in the population (since the individuals are diploid).
