Sources of Genetic Variation. 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.

en.wikipedia.org/wiki/Genetic_variation

Genetic variation is the difference in DNA among individuals or the differences between populations.There are multiple sources of genetic variation, including mutation and genetic recombination. The mutation is the ultimate source of genetic variation, but mechanisms such as sexual reproduction and genetic drift contribute to it as well.

Genetic variation enters a population from one of four sources: recombination, mutation, migration, or lateral gene transfer. Mutation rates can be measured in many ways and differ across species and even across different tissue types in the same species.

There are three sources of genetic variation in sexual reproduction. Which is not considered random? a. All are random. b. Crossing over c. Egg and sperm fertilization d. Tetrad alignment on the meiotic spindle.

It is obviously another source of genetic variation in offspring. This is known as random fertilization. All of these mechanisms working together result in an amazing amount of potential variation. Each human couple, for example, has the potential to produce more than 64 trillion genetically unique children. No wonder we are all different!

Three Primary Sources of Genetic Variation 1. Mutations are changes in the DNA. A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations. 2. Gene flow is any movement of genes from one population to another and is an important source of genetic variation. 3. Sex can introduce new gene combinations into a population.

Transfer of genetic material between populations is also an important contributor to genetic variation; populations in isolation are at risk of inbreeding and the amplification of harmful mutations. Organisms that reproduce sexually have a much higher degree of genetic variation than do asexual reproducers.

1) Sexual reproduction - causes variation because you create a new person by mixing the DNA of 2 unrelated individuals. 2) Independent segregation - When meiosis occurs to produce gametes, each gamete only gets one copy of each pair of homologous chromosomes and which one it gets is random with equal chance of getting either.

Without genetic variation, some of the basic mechanisms of evolutionary change cannot operate. There are three primary sources of genetic variation, in short are. Mutations are changes in the DNA. A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations.
