Answer :
A quantitative trait is a phenotypic trait that can be measured and is influenced by a variety of environmental factors and several genes.
A continuous distribution of phenotypes might result from these features, which can vary between people over a wide range. Measurements like height, weight, and blood pressure are examples. Quantitative genetic diversity serves as the basis for phenotypic development in wild populations as well as for selective breeding of domesticated plant and animal species. The likelihood of developing prevalent complicated diseases, behavioural abnormalities, and responses to pharmacological treatments are all influenced by quantitative genetic variation in people. increasing the rate of selective improvement of agriculturally important species, developing novel and more personalised therapeutic approaches, and maintaining genetic variation for quantitative traits within populations and the mechanisms of quantitative trait divergence between populations and species interventions to improve human health.
