Migration can lead to changes in allele frequencies by introducing new alleles into a population. When individuals move between populations, they bring their genetic material with them, potentially altering the genetic diversity of the receiving population. Gene flow through migration can increase genetic variation within a population or decrease differences between populations.
What else can I help you with?
Which term describes a change in the gene pool due to migration?
The term that describes a change in the gene pool due to migration is "gene flow." Gene flow occurs when individuals from one population migrate and breed with individuals from another population, introducing new genetic material and altering the allele frequencies within the gene pool. This process can enhance genetic diversity and reduce differences between populations.
What is a change in the allele frequiencies of a population due to the migration of a small subgroup of the population to a new place?
Genetic drift. The subgroup is subject to the founder effect.
Are allele frequencies more likely to remain stable in large populations than in small populations?
Yes, allele frequencies are more likely to remain stable in large populations due to the effects of genetic drift being more pronounced in small populations. In small populations, random events can lead to significant changes in allele frequencies, whereas in large populations, genetic drift has less impact and allele frequencies are more likely to remain stable over time.
What causes an allele frequency to go up in one generation and back down in the next generation?
There are three basic reasons: 1. Natural Selection-- thr environment may have favored the allele in previous generations, but now disfavors it. 2. Genetic Drift-- in every finite population, the frequency of an allele will fluctuate due to chance. For example, the vast majority of sperm fail to fertlize any egg, so allels can be lost this way due to chance. Individuals carrying a copy or copies of an allele may die young due to random accidents, or may never find a mate. These basic chance events cause the frequencies of alleles to fluctuate, and the degree of frequency change depends upon the population size. The greater the population size, the smaller the change in frequency. 3. A combination of both.
Which is an example of a genetic drift?
allele frequencies change randomly each generation ~*Apexx*~
When microevolution occurs what kind of frequencies change?
allele
What do biologist call the process when allele frequencies in a population of a species change over time due to change?
FOR PENNFOSTER....the answer is C) genetic drift
What do biologists call the process when allele frequencies in a population of a species change over time due to chance?
genetic drift

What are the changes of allele frequency in a small population that is due to random chance and don't follow the laws of probability?
Random changes in allele frequency are due to genetic drift.
Under ideal conditions how do allele frequencies change over time?
Under ideal conditions, allele frequencies can change over time due to genetic drift, natural selection, gene flow, and mutations. These factors can cause certain alleles to become more or less common in a population, leading to changes in allele frequencies. Over many generations, these changes may result in evolution occurring within the population.
How do allele frequencies change in Hardy-Weinberg equilibrium?
In Hardy-Weinberg equilibrium, allele frequencies remain constant from generation to generation if certain conditions are met. These conditions include no mutation, no gene flow, random mating, a large population size, and no natural selection. If these conditions are not met, allele frequencies can change due to factors such as genetic drift, gene flow, mutation, non-random mating, or natural selection.
The situation in which allele frequencies of a population remain constant is called?
That situation is called a Hardy-Weinberg equilibrium. Not actually seen outside of the lab.
What is Generation-to-generation change in the allele frequencies in a population?
Generation-to-generation change in allele frequencies in a population is known as evolution. This change can be the result of various factors such as natural selection, genetic drift, gene flow, and mutation. Over time, these processes can lead to the emergence of new traits and variations within the population.
How can under natural conditions cause allele frequencies to change?
Under natural conditions, allele frequencies can change due to various factors such as genetic drift, gene flow, natural selection, mutation, and non-random mating. These mechanisms can lead to changes in the distribution of alleles within a population over time.
How do allele frequencies remain constant while genotype frequencies evolve over time?
Allele frequencies remain constant in a population when certain conditions are met, such as no mutations, no gene flow, random mating, a large population size, and no natural selection. Genotype frequencies can change over time due to factors like genetic drift, natural selection, and non-random mating. As long as the conditions for constant allele frequencies are maintained, the overall genetic makeup of the population remains stable even as individual genotypes may change.
What is a change in the allele frequiencies of a population due to the migration of a small subgroup of the population to a new place?
Genetic drift. The subgroup is subject to the founder effect.
