Hybridization is the cross between the homozygous plants resulting in the formation of the heterozygous individuals. The progeny will be having hybrid characters possessing two different allele of a gene. The inbreeding is the process of producing the progeny by crossing the genetically similar parents. It also occurs during the selfing of the plants. The inbreeding process results in the expression of the lethal and the recessive genes. The inbreeding causes the formation of the pure breeds.
