What increases genetic variation in animals?
Gene duplication, mutation, or other processes can produce new genes and alleles and increase genetic variation. New genetic variation can be created within generations in a population, so a population with rapid reproduction rates will probably have high genetic variation.
What would most likely increase genetic variation?
d the amount of genetic variation in a population. An increase in food and a decrease in predators would most likely genetic variation in a population.
Which environmental factor would likely lead to an increase in genetic variation in a population of squirrels quizlet?
Genetic variation will increase because of a new habitat and food source. A scientist has been tracking and studying a population of deer in Yellowstone National Park. He surveys the population every six months. Usually, the population is thriving and has a gene pool with a wide variety of traits.
What factors affect genetic variation?
Major causes of variation include mutations, gene flow, and sexual reproduction. DNA mutation causes genetic variation by altering the genes of individuals in a population. Gene flow leads to genetic variation as new individuals with different gene combinations migrate into a population.
