Q. 11. How do genes and chromosomes share similarity from the point of view of genetical studies?
By 1902, the chromosome movement during meiosis had been worked out.
Walter Sutton and Theodore Boveri, (1902) noted that the behaviour of chromosomes was parallel to the behaviour of genes and used chromosome movement to explain Mendel's Laws.
They studied the behaviour of chromosomes during mitosis (equational division) and during meiosis (reduction division). The chromosomes, as well as genes, occur in pairs and the two alleles of gene pair are located of homologous sites of homologous chromosomes.
Chromosome movement in meiosis nad germ cell formation in a cell with four chromosomes. Chromosomes segregate when germ cells are formed.
