Two key factors that can influence the alleles in a gene pool are mutation and natural selection. Mutations introduce new alleles into a population, creating genetic variation. Natural selection can affect allele frequencies by favoring traits that enhance survival and reproduction, leading to an increase or decrease in certain alleles over time. Additionally, gene flow and genetic drift can also impact allele distribution within a population.
What else can I help you with?
On what does the allelic frequency in a population depend?
The allelic frequency in a population depends on factors such as mutation rates, genetic drift, gene flow, and natural selection. These factors influence the proportion of different alleles within a population over time.
What is an example of a human trait caused by a single gene with multiple alleles?
An example of a human trait caused by a single gene with multiple alleles is the ABO blood group system. This system is determined by the presence of different alleles at the ABO gene locus, specifically A, B, and O alleles. The combinations of these alleles result in four possible blood types: A, B, AB, and O, illustrating how multiple alleles can influence a single trait.
Two different forms of the same gene are called?
Alleles
Which term describes the movement of alleles into out of a population?
Gene flow
The different forms of a trait that a gene may have are called?
Alleles
Term used for the different forms of a gene are?
alleles

Different forms of a gene are called what?
Different forms of a gene are called alleles. Genes are the ones that influence the traits that will be inherited in the DNA.
What is the significance of having two alleles of the same gene in an individual's genetic makeup?
Having two alleles of the same gene in an individual's genetic makeup is significant because it can determine the individual's traits and characteristics. Alleles are different forms of a gene that can influence how a specific trait is expressed. Having two alleles of the same gene can result in different combinations that can affect the individual's physical appearance, behavior, and susceptibility to certain diseases.
Different or alternative forms of the same gene are called?
Alleles are alternate forms of the same gene. A gene is the basic physical unit of heredity that is passed on from a parent to their children.
How alleles and genes related?
Genes and alleles are related because alleles are inside a gene. Genes are made up by alleles. A gene is DNA. The allele is like piece of DNA inside a gene.
Different forms of a gene?
the alternative form of a gene is called an "allele."
Two different forms of the same gene are called?
Alleles
How do alleles influence natural selection?
It's the other way around: natural selection is the natural process that causes the frequencies of occurence of alleles in the population gene pool to shift.
Which term describes the movement of alleles into out of a population?
Gene flow
