Genetic variation is a direct results of many sources of genetic material and their unconstrained interaction. The larger the population and the fewer restrictions on how they can be integrated the more diverse the genetic variation. This allows for better natural selection and also reduced the ability of disease from affecting the entire population.
The founder effect describes genetic variation in communities established by few people.
Inbreeding in small closed communities leads to abundances of recessive ailments. This can be seen in hereditary royal families and closed remote communities.

Meiosis leads to variation in offspring by what?
In prophase of meiosis, first, a stage comes (known as crossing over) in which homologous chromosomes, after pairing, exchagne their genetic material. This is the stage where varition occurs during, and only in, meiosis I.
What is relationship between recombination frequency and genetic distance?
As genetic distance increases, the recombination frequency first increases in a linear fashion, but then levels off to a frequency of 0.5.
What type of cell division increases genetic variability?
Meiosis
What phase in meiosis increases genetic variation?
Crossing-over
What process in meiosis increases genetic variation?
The process of meiosis increases genetic variability as it produces Answers.com for Answers.com. Each Answers.com receives half the Answers.com of the parent Answers.com; the half it receives is randomly assorted.
Which increases genetic variation?
Mutations
Which process is a source of varition of organism?
On a cellular level you have random union (of sperm and oocyte), genetic crossover (crossover during meiosis 1), and the independent assortment of homologous chromosomes. On a larger scale you have things such as genetic drift and natural selection that will impact the variation in organisms.

Why is crossing over so important?
It increases genetic variation in organisms
What usually increases the appearance of a genetic disorder?
inbreeding.
What is relationship between recombination frequency and genetic distance?
As genetic distance increases, the recombination frequency first increases in a linear fashion, but then levels off to a frequency of 0.5.
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
What type of cell division increases genetic variability?
Meiosis
What phase in meiosis increases genetic variation?
Crossing-over
What type of reproduction helps increase the genetic material of a cell?
Sexual reproduction increases the genetic material of a cell.
What process in meiosis increases genetic variation?

The influence of genetic drift on allele frequencies increases as?
population size decreases
