(C) Heterosis or hybrid vigor refers to the phenomenon where the progeny of a cross between two genetically diverse parents exhibits superior traits compared to the parents.In sexually reproducing plants,this vigor is lost in subsequent generations due to segregation and recombination during meiosis.However,in vegetatively propagated plants,the hybrid genotype is maintained indefinitely through asexual reproduction (cloning).Therefore,once a superior hybrid is developed,it can be propagated vegetatively to preserve its heterosis without the risk of losing it through sexual recombination.
