Phenotypic variation in humans is a direct consequence of genetic variation, which acts in conjunction with environmental and behavioral factors to produce phenotypic diversity. Genetic variants are classified by two basic criteria: their genetic composition and their frequency in the population.

What is the ultimate source of phenotypic variation?
So, the correct option is 'Mutation'.
What are the possible causes of phenotypic?
Phenotypes can be caused by genes, environmental factors, or a combination of both. Phenotypic variation, then, is the variability in phenotypes that exists in a population. For example, people come in all shapes and sizes: height, weight, and body shape are phenotypes that vary.
What are the sources of phenotypic variation?
The phenotypic variation in populations is the result of genetic variation and two nongenetic sources of variation, namely, environmentally induced variation (EIV) and stochastic developmental variation (SDV).

What is the major source of variation?
Mutations.
What is the greatest source of genetic variation?
The ultimate source of genetic variation is random mutation - changes in nucleotide sequences of DNA. They may involve only a single base pair - as in (A), or many - as in chromosomal mutations (B).
What is the main source for genetic variation?
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.
Phenotypic Variation
What are two main sources of genetic variation?
Natural selection acts upon two major sources of genetic variation: mutations and recombination of genesrecombination of genesGenetic recombination (also known as genetic reshuffling) is the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.https://en.wikipedia.org › wiki › Genetic_recombinationGenetic recombination - Wikipedia through sexual reproduction.
What are the 2 main causes of genetic variation in populations?
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.
