Genetic diversity in a population comes from two main mechanisms: mutation and sexual reproduction. Mutation a change in DNA is the ultimate source of new alleles or new genetic variation in any population. The genetic changes caused by mutation can have one of three outcomes on the phenotype.

What is the ultimate source of organic variation?

Mutation is the ultimate source of variation.

What is the ultimate source of food on earth?

The ultimate source of the energy in food is the sun. The movement of energy from the sun through different organisms is what creates a food chain….

Where is the most genetic variation found?

sub-Saharan AfricaThe greatest divergence between populations is found in sub-Saharan Africa consistent with the recent African origin of non-African populations. Populations also vary in the proportion and locus of introgressed genes they received by archaic admixture both inside and outside of Africa.

Which human populations have the highest levels of genetic variation?

Results. Gene-diversity levels for each continental population are given in table 1. The most notable pattern is that Africans have the highest level of diversity for all types of systems except the nuclear RSPs for which Europeans have the highest level of diversity.

Which group has the most genetic variation quizlet?

The most human genetic variation and diversity exists in African populations which shows striking agreement with fossil evidence.

What is the source of variation in a population?

For a given population there are three sources of variation: mutation recombination and immigration of genes.

What are two main sources of genetic variation which are more common?

Natural selection acts upon two major sources of genetic variation: mutations and recombination of genes through sexual reproduction. Most mutations do not affect the reproductive fitness of individuals — some may be beneficial some may be harmful and many may be neutral.

Where do new variations come from quizlet?

Genetic variation comes from three different sources in nature mutation recombination and hybridization.
