Question

Wide hybridisation is
A. Intergeneric hybridization
B. Pollen stimulation of embryo development without fertilization
C. Random or unrestricted hybridization
D. Both A and C

Answer 1

Hint: Hybridisation is a process of combining different varieties of organisms to create a hybrid. A hybrid is a combination of two different things or we can say arises from any of mixed origin or composition. In biology, hybridisation refers to the process of producing an offspring by mating two parents from the different varieties or species.

Complete Answer:
- Wide hybridization is a cross which is made between the parents of two different species of the same genus. That’s why this cross is also called the interspecific cross.
- Wide hybridization is the pollen stimulation of embryo development without fertilization.
- Fertilization is a process in which the gametes (haploid) of two parents fuse with each other in order to form zygote which is diploid.
- Wide hybridization involves crossing of species from distant gene pools.

Additional information:
1. Intergeneric hybridization – Intergeneric hybridization is a cross between the parents of two different species belonging to different genera.
2. Random or unrestricted hybridization – Random or unrestricted hybridisation involves the crossing of random breeds without any specific selection.

Hence, option C is the correct answer for this question.

Note: Interspecific hybridization of wide hybridization is an important or useful method for the plant breeders in order to create new plants or to introduce genes from related wild species into the crops of interest. The newly created species may be of great economic importance.
