In recombination, cross-overs exchange alleles between homologous chromosomes during meiosis in both parents. This is what allows for much of the genetic variation in the offspring of a population in each generation.
Sexual recombination works in three different ways. First, chromosomes of the male and female exchange genetic material in the process of crossing over. Secondly, the tetrads in meiosis have two different ways to independently orient themselves in prophase I, And lastly fertilization is a completely random process.

How does genetic recombination influence how species change over time?
The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.
Other sources of genetic variation in a population are?
Mutations (ubiquitous) and genetic recombination (sexual reproduction only).
How does genetic combination help a species to survive?
It causes diversity and variation amongst a population
What factors contributes to genetic variation between humans?
the genes that code for RNA and proteins...............
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
Which of these is NOT a source of genetic recombination and variation?
A piece of volcanic rock.
What is the advantage of genetic recombination as a mode of reproduction in bacteria?
greater genetic variation. (e2020 answer)
What are two sources of genetic variation?
Natural and Artificial Selection
Is genetic recombination a major source of variation among organisms?
Yes.
What are sources of genetic variation in sexually - reproducing organisms?
meiosisHuman recombination
How does genetic recombination influence how species change over time?
The genetic variation introduced during recombination provides new allelic combinations for natural selection to act upon.
Other sources of genetic variation in a population are?
Mutations (ubiquitous) and genetic recombination (sexual reproduction only).
What are two main sources for genetic variation in a population?
Mutation and the genetic recombination in sexually reproducing organisms.
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 the cause of variation in the offspring of sexually reproducing organisms?
recombination of alleles
What is inhereited variation with recombination and gene flow?
What is inertied variation with recombination .
