What else can I help you with?
What causes genetic variation in a species?
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
What common genetic variation which causes a change in the amino acid sequence in the structure of hemoglobin leads to what disease?
Sickle cell
Genetic variation is a necessary condition of which process?
Genetic variation is one of the conditions required for Natural Selection to occur.
What increases genetic variations?
A large population increases genetics variation. Mutation will also increase genetics variation.
Breeders can increase the genetic variation by inducing what?
The introduction of animals into a breeding population that are unrelated will increase genetic variation.
What characteristic within populations causes natural to occur?
genetic variation
What is One consequence of genetic drift is?
Loss of genetic variation(:Novanet:)
What causes genetic variation in a species?
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
Is it possible for a population to undergo natural selection?
No, there is no genetic variation upon which natural selection can operate.
How do you use Genetic Variation in a sentence?
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."
Why is genetic variation important for natural selection to drive evolution?
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
What is a source of genetic variation in organisms?
Human recombination is a significant source of genetic variation.
What event in meiosis leads to genetic variation in organisms?
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.
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.
What common genetic variation which causes a change in the amino acid sequence in the structure of hemoglobin leads to what disease?
Sickle cell
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.
