Yes but it could also spread deleterious mutations. It depends on the size of the gene pool.

Yes, gene flow can spread advantageous mutations by introducing them into new populations. This can help increase genetic diversity and lead to adaptation to changing environments. However, if the advantageous mutation is already present in the recipient population, gene flow may not have a significant impact on spreading it.

What causes genetic divercity in animals?
Genetic diversity in animals comes from mutations, genetic recombination, and gene flow. Mutations are random changes in DNA, while genetic recombination occurs during crossing over in meiosis. Gene flow happens when individuals migrate and interbreed with other populations, introducing new genetic variations.
What are three main types of gene mutations what happens in each gene?
The three main types of gene mutations are point mutations, insertion mutations, and deletion mutations. Point mutations involve changes to a single nucleotide base. Insertion mutations involve the addition of extra nucleotide bases. Deletion mutations involve the removal of nucleotide bases in a gene sequence.
How mutation can change the gene pool?
Mutations introduce new genetic variations into a population, which can affect the gene pool by altering allele frequencies. Mutations can create new alleles or change existing ones, leading to increased genetic diversity within the population. Over time, if these mutations are advantageous, they can become more common in the gene pool through natural selection, impacting the overall genetic composition of the population.
Which term describes the movement of alleles into out of a population?
Gene flow
Are mutations the only way to add new genes to a gene pool?
No, mutations are not the only way to add new genes to a gene pool. Gene flow, which involves the movement of genes between populations, can also introduce new genetic variation. Additionally, genetic recombination during sexual reproduction can shuffle existing genes to create new combinations.
Can you list Two sources of variation?
Mutations, recombination, gene flow.
What happens to any population when its small and isolated from gene flow?
Mutations
Why do variations exist in populations?
Variations exist in populations due to genetic diversity resulting from mutations, recombination, and gene flow. These variations provide a pool of different traits that can be advantageous in changing environments, driving evolution and adaptation.
How does gene flow affect the fitness of population?
Gene flow within a population distributes mutations among the individuals. Immigration and emigration transport alleles into and out of a population's gene pool, thus affecting the result of natural selection.

Gene flow happens when individuals migrate and interbreed with other populations, introducing new genetic variations.
What causes the allele frequencies to changes?
1. Mutation 2. Migration (Gene Flow): both immigration and emigration. 3. Genetic Drift 4. Sexual Selection (Non-random mating) 5. Natural Selection: those most fit survive to pass on their genes to the next generation.

What is the source of genetic variation?
Genetic variation arises from mutations, genetic recombination during meiosis, and gene flow between populations. Mutations are changes in the DNA sequence, while genetic recombination mixes genetic material from two parents during sexual reproduction. Gene flow occurs when individuals migrate between populations, introducing new alleles into a gene pool.
Mutations are not able to cause things to evolve because?
Whoa. Mutations usually cause things to evolve, depending on the gene which is mutated. Mutations are changes in the genetic material of an organism resulting in changes in the gene pool (if the mutated traits are passed on). If the mutated gene is a desirable/advantageous one, then the chances that it willbe passed on to future generations is increased. In this process, which occurs over a period of time, old genes may be lost in the gene pool, resulting in evolution. I don't see how it doesn't cause evolution.
What is the cause of improper functions of a gene?
gene mutations
How mutation can change the gene pool?
Mutations introduce new genetic variations into a population, which can affect the gene pool by altering allele frequencies. Mutations can create new alleles or change existing ones, leading to increased genetic diversity within the population. Over time, if these mutations are advantageous, they can become more common in the gene pool through natural selection, impacting the overall genetic composition of the population.
What is driver mutation?
The mutations that confer a selective growth advantage to the tumor cell are called “driver” mutations. It has been estimated. A driver gene is one that contains driver gene mutations. But driver genes may also contain passenger gene mutations A typical tumor contains two to eight of these "driver gene" mutations; the remaining mutations are passengers that confer no selective growth advantage.
