Why is crossing over so important?
It increases genetic variation in organisms
Why genetic variation is a benefit to a population?
Genetic variation allows a population to adapt to a changing environment.
What is heritable variation?
Heritable variation is the variation in characteristics caused by genetic factors.
What would decrease genetic variation in a population?
When there is low genetic variation in a population the species produced are unlikely to withstand diseases.
What is the source of genetic variation?
Mutation.
What is One consequence of genetic drift is?
Loss of genetic variation(:Novanet:)
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
Relate genetic variation and mutations to each other?
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.
Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?
Genetic variation
Why is crossing over so important?
It increases genetic variation in organisms
Why genetic variation is a benefit to a population?
Genetic variation allows a population to adapt to a changing environment.
What the three ways to represent a direct variation?
equation, table or a graph
What contributes to genetic variation?
The patterns of nitrogenous bases in DNA encoded on the genes creates genetic variation.
Is Natural selection a source of genetic variation in a population?
No, natural selection works on that genetic variation presented to it.
Do you no two examples of Inherited variation?
genetic and environmental variation
Genetic variation occurs when chromosomes are shuffled in and fertilization?
genetic variation occurs when chromosomes are shuffled in_and fertilization
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
