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.
What are two sources of genetic variation?
Natural and Artificial Selection
Is an altered gene in a zygote inheritable?
Yes, an altered gene in a zygote can be inheritable as it becomes part of the offspring's genetic makeup. This alteration can be passed on to future generations through the germline cells.
What process produces new alleles of a gene?
Mutations are the main process that produces new alleles of a gene. Mutations can arise from errors during DNA replication, exposure to environmental factors like radiation or chemicals, or through genetic recombination during meiosis. These new alleles can introduce genetic variation into a population.
Deletion is when a whole segment of a gene is?
Deletion occurs when a whole segment of a gene is lost.

What are the two types of gene shuffling?
Gene shuffling means the genetic recombination and mutations of a gene pool of a species where genetic recombination is the mixture of parent alleles that are passed on and the mutations are the random changes in an organisms DNA that are passed on.
What is new gene combinations?
when genes cross over during meiosis, then split they from genes that differ.
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.

How can events result in inheritable genetic variations in organisms?
Events such as mutations, gene flow, and genetic recombination can lead to inheritable genetic variations in organisms. Mutations are random changes in DNA sequences that can introduce new traits. Gene flow occurs when individuals from different populations interbreed, introducing new alleles into a gene pool. Additionally, during sexual reproduction, genetic recombination shuffles genes, creating unique combinations that can be passed on to offspring.
What makes new gene enter a population?
New genes can enter a population through several mechanisms, the most notable being mutation, gene flow, and genetic recombination. Mutations introduce new alleles, while gene flow occurs when individuals migrate between populations, bringing new genetic material. Additionally, genetic recombination during sexual reproduction can create new gene combinations, contributing to genetic diversity. These processes collectively enhance the genetic variation within a population, allowing for adaptation and evolution over time.
What evolutionary forces could create new genetic information in a population?
Mutation, gene flow, and genetic recombination are evolutionary forces that can introduce new genetic information into a population. Mutation is the primary source of genetic variation by creating new alleles. Gene flow allows for the movement of genetic material between populations, introducing new alleles. Genetic recombination during sexual reproduction can also create new combinations of genes, increasing genetic diversity.
What also contributes to genetic variation?
The two main sources of genetic variation are gene shuffling and mutations. A mutation is a process wherein the structure of a gene is altered.
