Question

Give reasons for hybridisation increases crop yield

Answer 1

Hybridization is the crossing of dissimilar individuals to produce best of both organisms. It might be of interbreeding between individuals of different species (interspecific hybridization) or genetically divergent individuals from the same species (intraspecific hybridization). One advantage of hybridization is that it can combine disease resistance of one organism with the production capacity of another.

Crop yields increase dramatically when hybridization is used to exceed one or more of the parents in size and reproductive potential

Answer 2

Hybridisation increases the crop yield because after this process the crops are now disease resistance and high yielding thus the crop yield inceases
