Anaphase 1 - the crossing over of chromosomes, they swap genetic material determining what you genetically inherit
parents cromsones
genetic variation happens because of meiosis. chromosomes are randomly in each sperm/egg cell, and so when they come together it's unlikely to get the same combination twice
Sickle cell
Genetic variation is one of the conditions required for Natural Selection to occur.
A large population increases genetics variation. Mutation will also increase genetics variation.
The introduction of animals into a breeding population that are unrelated will increase genetic variation.

It is possible for plants that have identical genetic make-up to show differences due to genetic causes of variation such as mutations,meiosis and sexual reproduction and environmental causes of variation such as nutrients,and temperature.
Genetic bottleneck causes very little genetic variation and can cause genetic drift.
the genetic variation isappearanceor the genes members of the same species of the same group.
Genetics refers to the study of genes, the microscopic biological building blocks that make us what we are. Used in a sentence: "The study of genetics is helping us to learn why certain diseases run in families."
It causes diversity and variation amongst a population
No, there is no genetic variation upon which natural selection can operate.
Genetic crossover occurs, which causes a sharing and transference of genetic information between maternal and paternal copies of chromosomes and further enhances the genetic variability of their offspring.
Human recombination is a significant source of genetic variation.
mutations cause genetic variation, and vice-versa. If there is a genetic variation (or lack of one), then this can effect the severity of the mutation.
