Mechanisms such as gene flow, mutation, genetic drift, and natural selection are all considered mechanisms for genetic variation. Non-genetic mechanisms, such as Lamarckian inheritance or acquired characteristics, are not considered valid mechanisms for genetic variation in the traditional sense.

What mechanism of evolution causes this change?

Mutation is the primary mechanism of evolution that leads to genetic variation within a population. This variation, along with natural selection, genetic drift, gene flow, and other forces, drives the changes observed in populations over time.


What process is responsible for genetic variation?

The process responsible for genetic variation is genetic recombination, which occurs during meiosis when genetic material is exchanged between homologous chromosomes. Mutations, which are changes in the DNA sequence, also contribute to genetic variation.


What is the significance of genetic variation after meiosis?

Genetic variation after meiosis is significant because it leads to the creation of unique offspring with diverse traits. This variation is important for evolution and adaptation to changing environments.


How do stabilizing and disruptive selection differ in terms of their impact on the genetic variation within a population?

Stabilizing selection maintains genetic variation by favoring the average traits, while disruptive selection increases genetic variation by favoring extreme traits.


How does standing genetic variation contribute to the overall genetic diversity within a population?

Standing genetic variation refers to the existing genetic differences within a population. This variation contributes to genetic diversity by providing a pool of different genetic traits that can be passed on to future generations. This diversity helps populations adapt to changing environments and increases their chances of survival.

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.


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.


Which of these is necessary for natural selection to occur genetic engeneering genetic variation asexual reproduction or enviormental stability?

Genetic variation is necessary for natural selection to occur. This variation provides the raw material for differential survival and reproduction, which drives the process of natural selection. Without genetic variation, there would be no differences for natural selection to act upon.


Do you no two examples of Inherited variation?

genetic and environmental variation

Genetic variation is a necessary condition of which process?

Genetic variation is one of the conditions required for Natural Selection to occur.


What do stabilization selection and disruptive selection have in common?

They both decrease genetic variation. Stabilizing selection and disruptive selection reduce genetic variation


What id genetic variation?

Genetic Variation is a measure of the genetic differences there are within populations or species. For example, a population with many different alleles at a locus may be said to have a lot of genetic variation at that locus. Genetic variation is essential for natural selection to operate since natural selection can only increase or decrease frequency of alleles already in the population
