Results In Genetic Variety. Definition of Genetic Diversity Genetic diversity is the diversity or variability within species community or assemblage. Genetic variability is a measure of the tendency of individual genotypes in a population to vary become different from one another.
Sexual reproduction increases genetic variation in offspring which in turn increases the genetic variability in species. Thus one can define biodiversity as the degree of variety in nature with regards to biological species. Each single nucleotide polymorphism represents a difference in a single DNA base A C G or T in a persons DNA.
Mutations lead to genetic variation by altering genes and alleles in a population.
It occurs at 3 different levels namely species diversity genetic diversity and ecosystem diversity. Genetic variation is the result of mutation gene flow between populations and sexual reproduction. Thus one can define biodiversity as the degree of variety in nature with regards to biological species. Genetic diversity serves as a way for.
