Role of SNPs in determining QTLs for major traits in cotton
By Muhammad Naveed Arshad on Nov 29, 2019


A single nucleotide polymorphism is the simplest form of genetic variation among individuals and can induce minor changes in phenotypic, physiological and biochemical characteristics. This polymorphism induces various mutations that alter the sequence of a gene which can lead to observed changes in amino acids. Several assays have been developed...
