POPULATION AND PURE LINES CONCEPT

Abstract

This article provides a comprehensive overview of the concepts of populations and pure lines in genetics, two fundamental terms widely used in the fields of biology, genetics, plant and animal breeding, and evolutionary studies. A population refers to a group of individuals of the same species living in a shared environment, which interbreed and collectively form a gene pool with varying alleles. In contrast, a pure line is a genetically uniform line, often developed through continuous inbreeding or self-pollination, where individuals are homozygous for specific traits. Understanding the structure, characteristics, and applications of both populations and pure lines is crucial for researchers and practitioners aiming to enhance genetic variation, stability, and selective breeding programs. This article discusses their biological significance, differences, advantages, disadvantages, and their practical applications in agriculture and genetics research.
