Variation in alleles affects the adaptability of the organism, its physiological development, and its ability to survive and reproduce in different environmental conditions.

Alteration in DNA sequences due to mutations can produce different alleles. Genetic diversity is present within a population because individuals have different genes due to slight differences in their DNA sequences. The extent of genetic variation among individuals is variable. Some of these individuals may mate and produce offspring. The interaction of the environment and genes are responsible for the extent of diversities among individuals in a population.Ī population may consist of a small or a large number of individuals. When left to reproduce, there is a high tendency that the offspring will similarly express the unfavorable trait because of the high chance of inheriting the gene causing it due to a low diverse gene pool.Īpart from genetic diversity, another source of diversity within species or within a population is the environment. This is because unfavorable traits, such as inherited diseases, may become widespread within a population. Conversely, the lower the genetic diversity within a species, the lower is the chance of survival. The greater the genetic diversity within a species, the greater is the chance of that species to survive. Species with a higher diversity have a lower tendency to become extinct. The extent of these diversities is engendered by genetic diversity. All differences within species originate from the diversity of their genes. The diversity of species is a fundamental aspect of a healthy ecosystem. Ecosystem diversity refers to the presence of different ecosystems in a certain place species diversityis defined as the presence of different species in a given region. Other terms that are relevant to this topic include “ecosystem diversity” and “species diversity”. Many researchers define genetic diversity as the amount and extent of genetic variability among populations whereas biodiversity refers to the diversity of all organisms in a given ecosystem at a given time. The term biodiversity refers to the biological diversity of life on Earth and therefore that includes multifarious microorganisms, plants, and animals along with their genes and their respective environments or habitats. What is the impact of genetic diversity on biodiversity? Genetic diversity is the main contributor to biodiversity in an ecosystem. Conversely, the term “genetic diversity” expresses the total number of variations. Apart from mutation, other mechanisms leading to genetic variation are sexual reproduction and genetic drift. The variation may result from a mutation mutations may cause the emergence of mutants or variants.

Genetic variation simply refers to the variation of genomes at the individual level (i.e., between individuals) or at the species level (i.e. How about genetic variation? What is it? Genetic variation is defined as the presence of a various number of alleles with different distribution frequencies in a certain population. Genetic variability is defined as the tendency of a population to produce organisms with different genotypes. To further understand genetic diversity, let us define related terms. Genetic diversity, variability, and variation For instance, the population of dogs may consist of different breeds of dogs. Apart from between species, genetic diversity may also be observed among species. For example, the population of humans consists of individuals with different physical traits reflecting their genetic diversity.

A population would have different genes that are responsible for the variation among its members. These genes are responsible for the expression of their distinct features since these genes control the differences and similar characteristics among different organisms. It refers to the nucleotide sequence in the DNA strands packaged in chromosomes. A geneis the inheritance unit by which generations can inherit the features of their parents. Genetic diversity, variability, and variationĮach species is composed of individuals with their own set of genes.
