Mating between individuals of various species or genera that results in the merging of divergent genomes into a single nucleus is known as distant or wide hybridization. The species barrier to gene transfer is broken by this procedure. It allows the entire genome of one species to be transferred to another, causing changes in the progenies' genotypes and phenotypes. Natural remote hybridization and speciation have produced many of today's crop plants. Many allopolyploid species are the result of broad hybrids doubling their chromosomes. Backcrossing broad hybrids to their parents on a regular basis is another method of gene introgression. This occurs when chromosomes or chromosomal fragments from one species infiltrate into another.
