Stream of consciousness: The important part for answering this question is: Human impact on the environment has resulted in an increase in the intrabreeding between species, with introduced species worldwide, which has resulted in an increase in hybridization.
Q: Human impact on the environment has resulted in an increase in the intrabreeding between species, with introduced species worldwide, which has resulted in an increase in hybridization. The genetic mixing may threaten many species with extinction, while genetic erosion in crop plants may be damaging the gene pools of many species for future breeding. Many commercially useful fruits, flowers, garden herbs and trees have been produced by hybridization. One flower, Oenothera lamarckiana, was central to early genetics research into mutationism and polyploidy.

Answer this question: crossing of two parents belonging to different species is called?
A: hybridization
