Let us say you have three alleles in a population of beetles. Two colors; brown is recessive to green. Thus you have; GG, which is homozygous dominant and green, you have Gb, which is heterozygous and also green. Then you have bb, which is homozygous recessive. This is your population of beetles.
What do you think the allele frequency would be if GG, the homozygous dominant, either immigrated, or emigrated out of or into your population of beetles? Since the frequency of Gb and bb would necessarily go down statistically you would see more green morphologies and a change in genetic allele frequency. Assuming normal conditions.
What else can I help you with?
The allele frequencies of a population are more likely to remain unchange if?
There is no evolution. Random mating, no immigration/emigration, or, in short, Hardy-Weinberg equilibrium holds.
A population in which allele frequencies do not change from generation to generation is said to be in?
A population in which the allele frequencies do not change from one generation to the next is said to be in equilibrium.
What is the type of equilibrium that occurs when allele frequencies do not change?
The type of equilibrium where allele frequencies do not change is called Hardy-Weinberg equilibrium. This equilibrium occurs in an idealized population where certain assumptions are met, such as random mating, no mutation, no migration, no natural selection, and a large population size. In Hardy-Weinberg equilibrium, the genotype frequencies can be predicted using the allele frequencies.
Would a dominant allele ever return to a population?
If a population does not have a particular dominant allele, it could return to the population through the immigration of new individuals carrying the dominant allele.
What are allele frequencies used for?
Allele frequencies are used to study genetic variation within a population. They can provide information about the genetic diversity, evolution, and potential for certain traits or diseases in a population. By tracking changes in allele frequencies over time, researchers can gain insights into how populations evolve and adapt to their environments.

What is the method to calculate allele frequencies for a specific gene in a population?
To calculate allele frequencies for a specific gene in a population, you can use the formula: allele frequency (number of copies of a specific allele) / (total number of alleles in the population). This helps determine how common a particular allele is within the population.
If the actual allele frequencies in a population do not match genotype frequencies predicted by the Hardy Weinberg equation what is the population?
The population is evolving.
A population in which allele frequencies do not change from generation to generation is said to be in?
A population in which the allele frequencies do not change from one generation to the next is said to be in equilibrium.
What is the process called when allele frequencies in a population of a species change over time?
Evolution; the change in allele frequencies over time in a population of organisms.
What does it mean for a population to be in genetic equilibrium?
A population is in genetic equilibrium when allele frequencies remain constant over generations, indicating that there is no evolution occurring. This suggests that the population is not experiencing any genetic drift, gene flow, mutations, or natural selection.

Would a dominant allele ever return to a population?
If a population does not have a particular dominant allele, it could return to the population through the immigration of new individuals carrying the dominant allele.
Do Stable allele frequencies prevent microevolution?
No, stable allele frequencies do not prevent microevolution. Microevolution involves changes in allele frequencies within a population over time, even if those frequencies are stable for a period. Evolution can still occur through mechanisms such as genetic drift, selection, and gene flow, even if allele frequencies are temporarily stable.
What are allele frequencies used for?
Allele frequencies are used to study genetic variation within a population. They can provide information about the genetic diversity, evolution, and potential for certain traits or diseases in a population. By tracking changes in allele frequencies over time, researchers can gain insights into how populations evolve and adapt to their environments.
What is a situation in which allele frequencies remain constant?
Equal fitness in a population
What is genetic equilibrium and how does it describe a population in which the allele frequencies remain constant and do not change over time?
Genetic equilibrium is a state in which the allele frequencies in a population remain constant and do not change over time. This means that the population is not evolving and there is no change in the genetic makeup of the population.
