What else can I help you with?
The frequencies of alleles and genotypes remain constant from generation to generation unless?
Unless there are factors such as mutation, genetic drift, gene flow, or natural selection that can cause changes in allele frequencies within a population. This concept is known as the Hardy-Weinberg equilibrium, which describes the conditions under which allele and genotype frequencies remain stable over time in a population.
What parts of the Hardy Weinberg equation represent gene frequency?
The p and q variables in the Hardy-Weinberg equation represent the frequencies of the two alleles in a population. The equation is often written as p^2 + 2pq + q^2 = 1, where p and q represent the frequencies of the dominant and recessive alleles, respectively.
How to solve a Hardy-Weinberg problem?
To solve a Hardy-Weinberg problem, you need to use the formula p2 2pq q2 1, where p and q represent the frequencies of two alleles in a population. First, determine the allele frequencies using the given information. Then, use the formula to calculate the expected genotype frequencies. Compare the expected and observed genotype frequencies to determine if the population is in Hardy-Weinberg equilibrium.
When a population is not evolving what is it called?
When a population is not evolving, it is called being in genetic equilibrium. This means that the frequency of alleles in the population remains constant from generation to generation. Evolution requires changes in allele frequencies, so genetic equilibrium indicates no evolution is occurring.
What happens when a population in hardy weinberg equilibrium?
The phenotype frequency does not change

What happens when a population in hardy weinberg equilibrium?
The phenotype frequency does not change
Allele frequencies in a population tend to remain the same from generation to generation unless acted on by outside influences?
Genetic equilibrium is a theoretical concept used to study the dymamics of single alleles in the population gene pool. In practice, there is no situation in which allele frequencies do not drift to some degree. Large populations may slow drift down, but there will still be drift.
How do you work out Hardy Weinberg problems?
To work out Hardy-Weinberg problems, you need to first identify the frequencies of the alleles in a population. Then, you can use the Hardy-Weinberg equation (p^2 + 2pq + q^2 = 1) to calculate the frequencies of genotypes and phenotypes in the population. Remember that p represents the frequency of one allele and q represents the frequency of the other allele in the population.
What does being in Hardy-Weinberg equilibrium mean for a population?
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. When mating is random in a large population with no disruptive circumstances, the law predicts that both genotype and allele frequencies will remain constant because they are in equilibrium.
What is a sentence using hardy-weinberg principle?
According to the Hardy-Weinberg principle, the frequency of alleles in a population will remain constant from generation to generation as long as equilibrium is maintained through random mating, no gene flow, no genetic drift, no natural selection, and no mutations.
What idea did Hardly and Weinberg disprove?
Dominant alleles become more common in each generation
What question did hardy and Weinberg want an answer?
Hardy and Weinberg wanted to answer the question of how genetic variation is maintained in a population over time. They developed the Hardy-Weinberg equilibrium principle, which describes the expected frequencies of alleles in a population that is not undergoing any evolutionary changes.
What is the relationship between the frequencies of three alleles of a gene in a population, and how do they add up to a specific value?
The relationship between the frequencies of three alleles of a gene in a population is that they must add up to 1 (100). This is known as the Hardy-Weinberg equilibrium. The frequencies of the three alleles can be represented as p, q, and r, and the equation p q r 1 must hold true in a population for genetic equilibrium to be maintained.
