By the year 1900, due to improvements in cytological techniques and in the optical properties of microscopes, the behaviour of chromosomes in the cells was studied. William Sutton noticed striking similarities in the behaviour of chromosomes during […]

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 […]

Haploid organisms such as protists, fungi and algae have only one gene for a trait and will express the phenotypes of any kind of mutations because there is no hindrance of dominance. On the other hand, diploid organisms such as the Drosophila and pea have two alleles, one in each homologous chromosome. The haploid organisms […]
