Yes.
There are two general ways in which to
alter the genetic message encoded in
DNA. They are:
Mutation
• results from errors in replication
• can involve changes, additions, or deletions to
nucleotides
Recombination
• causes change in the position of all or part of a
gene

What are two sources of genetic variation?
Natural and Artificial Selection
What process produces new alleles of a gene?
There isn't ONLY one way, except for genetic manipulation (from an injected virus which is NOT for immunization); the only other way is via reproduction.
Is an altered gene in a zygote inheritable?
is an altered gene in egg is inheritable
What is the manipulation of genes for practical purposes?
Genetic manipulation is incorporation of new genes for various traits from other genotypes into the crop variety so as to bring about desired changes. It is carried out through hybridization, mutation breeding and DNA recombination technology.
Gene frequencies in a gene pool may shift randomly and by chance This is called?
Random changes.This would be called genetic drift.
What are two sources of genetic variation?
Natural and Artificial Selection
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 process produces new alleles of a gene?
There isn't ONLY one way, except for genetic manipulation (from an injected virus which is NOT for immunization); the only other way is via reproduction.
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.
Which process plays a part in genetic recombination?
Recombination in meiosis. Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. Recombination occurs randomly in nature as a normal event of meiosis and is enhanced by the phenomenon of crossing over, in which gene sequences called linkage groups are disrupted, resulting in an exchange of segments between paired chromosomes that are undergoing separation.
What is inhereited variation with recombination and gene flow?
What is inertied variation with recombination .
Is an altered gene in a zygote inheritable?
is an altered gene in egg is inheritable
If a certain species has little genetic variation what could lead to its rapid extinction?
Genetic bottleneck causes very little genetic variation and can cause genetic drift.
What is a gene that is altered or copied incorrectly called?
A gene that is altered or copied incorrectly is mutated.
Can you list Two sources of variation?
Mutations, recombination, gene flow.
How are the 2 forms of a gene distributed to the offspring?
Through recombination and then Mitosis.
