Is genetic variation found only in wild organisms in nature?
No.
What is essnetial to evolution?
Genetic and morphological variation. Without variation in organisms there would only be the shifts of genetic drift and gene flow in organisms. When organusms are varied then one can be selected from the other by the environment and the organisms ability to reproduce against that environment. Then there is evolution.
What typeof organisms can increase genetic variation through reproduction?
both plants and animals
What is genetic variation in natural selection?
Natural selection ' selects ' from among variations. Some organisms are better suited to their immediate environment and survive and out reproduce other organisms. All these organisms are genetically variant. That is the simple connection between natural selection and genetic variation. ( that variation coming about by mutation and recombination )
What do all organisms have that is invisible because it involves small differences in biochemical processes?
Genetic Variation
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
Why is crossing over so important?
It increases genetic variation in organisms
Which is a source of genetic variation in sexually-reproducting organisms?
Basic source of variation in all organisms is mutation .
Is genetic variation found only in wild organisms in nature?
No.
Is genetic recombination a major source of variation among organisms?
Yes.
What are sources of genetic variation in sexually - reproducing organisms?
meiosisHuman recombination
What are two main sources for genetic variation in a population?
Mutation and the genetic recombination in sexually reproducing organisms.

Increased genetic variation often helps organisms withstand changes in the?
Environment
Molecules responsible for hereditary and variation of organisms?
DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
What typeof organisms can increase genetic variation through reproduction?
both plants and animals
Sexual reproduction evolved before the evolution of?
Multicellular organisms
