Which one of the following methods is commonly used to maintain the genetic traits of a given plant ?
(a) By propogating through seed germination
(b) By propogating through vegetative multiplication
(c) By generating hybrids through intergeneric pollination
(d) By treating the seeds with gamma radiations
(b) The propogation through vegetative multiplication is used to maintain the genetic traits of a given plant. It gives rise to genetically uniform population or clone. In case of plants propogated through seeds, variations creep in due to chance segregation and recombination of genes during meiosis and their chance combination during fertilisation.
