Detailed explanation-1: -Genetic linkage describes the way in which two genes that are located close to each other on a chromosome are often inherited together. In 1905, William Bateson, Edith Rebecca Saunders, and Reginald C. Punnett noted that the traits for flower color and pollen shape in sweet pea plants appeared to be linked together.
Detailed explanation-2: -Listen to pronunciation. (LING-kij) The tendency for genes or segments of DNA closely positioned along a chromosome to segregate together at meiosis, and therefore be inherited together.
Detailed explanation-3: -Genes that are located on the same chromosome are called linked genes. Alleles for these genes tend to segregate together during meiosis unless they are separated by crossing over.
