Morgan formulated the chromosome theory of linkage according to which: a. Genes lie in a linear order in the chromosomes. b. The genes that are linked, stay on the same chromosome. c. The distance between the linked genes in the chromosome determines the strength of linkage. The closer the genes are located, stronger is the […]

In this article we will discuss about the introduction and significance of chromosome mapping. The diagrammatic representation of the relative distance between the linked genes of a chromosome is called linkage or genetic map. Since a linkage map is the outcome of crossing over studies, it is also called crossover map. The method of constructing […]
