Vedclass · Answer

(A) Heterosis or hybrid vigor refers to the phenomenon where the hybrid offspring shows superior traits compared to its parents. In sexually reproducing plants,this vigor is lost in subsequent generations due to segregation and recombination. However,in vegetatively propagated plants,the hybrid genotype is maintained indefinitely through asexual reproduction without the risk of segregation. Therefore,once a superior hybrid is developed,its heterosis can be preserved and multiplied rapidly through vegetative propagation.
