A change in the gene pool due to chance is called what?
A change in the gene pool due to chance is genetic drift.
What occurs during genetic drift?
Genetic drift is the random change in gene frequencies within a population due to chance events. It can lead to the loss of genetic diversity and the fixation of certain alleles in a population. Genetic drift is more likely to occur in small populations or isolated populations.
What is a change in the frequency of a particular gene in one direction in a population called?
A change in the frequency of a particular gene in one direction in a population is called genetic drift. Genetic drift refers to the random fluctuation of allele frequencies in a population over time, leading to a change in the genetic composition of the population.
How can genes be removed from the gene pool?
Genes can be removed from the gene pool through natural selection, genetic drift, and gene flow. Natural selection removes genes that are less advantageous for survival and reproduction over time. Genetic drift is the random change in gene frequency in a population due to chance events. Gene flow occurs when individuals migrate between populations and bring new genetic material, potentially diluting or replacing existing genes.
When chance changes in the gene pool of a small population is know as?
Genetic drift. This phenomenon is characterized by random changes in allele frequencies within a population due to chance events, such as natural disasters or population bottlenecks, especially in small populations.

Farmers change gene pool of a population by?
Artificial selection
What must occur for a gene pool within a population to change?
A genetic mutation within the population.
What causes a frequency in a population to change after each generation?
Gene mutation causes the phenotype frequency in a population to change after each generation.
What is genetic drift-?
Genetic drift is the random change in the frequency of alleles within a population's gene pool. It can cause the genetic composition of a population to change in one direction or another. Combined with natural selection, genetic drift is a principal force in biological evolution.Another Answer:Genetic drift is where random chance events which can effect the gene's abundance in a population, regardless of whether the gene is advantageous or not. For example, a natural disaster kills animals indiscriminately, regardless of their genetic makeup.
What is a change in the frequency of a particular gene in one direction in a population called?
A change in the frequency of a particular gene in one direction in a population is called genetic drift. Genetic drift refers to the random fluctuation of allele frequencies in a population over time, leading to a change in the genetic composition of the population.
What would happen is selective pressure changed and the recessive gene was selected for?
If selective pressure changed and the recessive gene was selected for, individuals carrying the recessive gene would have a higher chance of surviving and reproducing, leading to an increase in the frequency of that gene in the population. Over time, this could result in the recessive gene becoming the dominant trait in the population.
How can genes be removed from the gene pool?

When chance changes in the gene pool of a small population is know as?
Genetic drift. This phenomenon is characterized by random changes in allele frequencies within a population due to chance events, such as natural disasters or population bottlenecks, especially in small populations.
What is a change in a population over time that also changes the genes in the gene pool?
Evolution.
What does not change in a population unless outside factores affect the gene pool?
allelie frequencies
