What is Genetic Variation ?

Genes of organisms wihtin a population change. Gene alleles determine distincy traits the can be passes on from parents to offspring. Gene variation is important to the process of natural selevtion. the genetic variations that arise in a population happen by chance but the process of natural selection does not .

What is examples of Genetic Variation ?

Mutations are changes in the DNA . One mutation can have a large effect but in many cases evolutionary change is based on a accumulation.

Gene flow is any movement of genes from one population . this genetic shuffling is another important source of genetic variation .

Sex csn intoduce new gene combinations into population . this genetic shuffling is another important source of genetic variation .
