27. MECHANISMS OF SPECIATION

27.9. Interspecific Hybridization

This is a form of sympatric speciation in which a new species arises As a result of crossing between individuals of two distinct species. Fertile hybrids are produced in such cases only when interspecific Hybridization leads to a chromosomal mutation resulting in The formation of an allopolyploid (sec. 24.9.2). An example is the hybrid between cabbage and radish produced by G. D. Karpechenko. The genetic changes occurring during this type of hybridization are shown in Fig. 27.17.
