Explain the factor Chromosomal Inheritance?
A huge step forward in our understanding of heredity came in 1902, when a biologist named Walter S. Sutton proposed that Mendel's "factors" are carried on chromosomes. Sutton observed that chromosomes occurred in pairs that segregated during meiosis, one of each pair going to each gamete. He observed that the gametes contained only half the number of chromosomes in the adult organism. His observations explained the cellular basis for Mendel's laws of segregation and independent assortment.
