Crossing over of sister chromatids in prophase 1 of meiosis, independent assortment along the metaphase plate in metaphase 1 of meiosis.
Not sure what a third one is.
-------------------------------------------------------------------
There are more actually 4 causes that cause genetic variety even though mainstream high school Biology only discusses the three main ones: Crossing over, independent assortment (which happen during sexual reproduction), and, random genetic mutations.
The 4th one is gene transfer. Species transfer genes between them.

Other sources of genetic variation in a population are?
Mutations (ubiquitous) and genetic recombination (sexual reproduction only).
What two different sources of genetic variation in a plant or animal population?
The main source of genetic variation is a large population with a large gene pool.
What is the signifiance of the genetic variation and natural selection?
genetic variation (from any of several sources) provides options to try.natural selection determines which of those options help the population most.
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 of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation
What are two sources of genetic variation?
Natural and Artificial Selection
What are the two main sources of genetic variation and which of them is more common?
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.
What are sources of genetic variation in sexually - reproducing organisms?
meiosisHuman recombination
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.
What are the sources of genetic variation in plants and each of the major pathogen groups?
mutation

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.
Mutations and the genetic shuffling that occur during sexual reproduction are both sources of?
Mutations and genetic shuffling are two actions that occur during sexual reproductions. These scientific actions are both sources of genetic variation.
What is One consequence of genetic drift is?
Loss of genetic variation(:Novanet:)
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.
