According to the chromosomal theory of inheritance, the chromosomes possess Mendelian factors or genes. The chromosomes segregate and assort independently during meiosis and recombine in zygote at the time of fertilisation. Chromosomes, like genes occur in pairs. The two alleles of a gene pair are located on homologous sites on homologous chromosomes.
