Question

Which one of the following methods is commonly used to maintain the genetic traits of a given Plant?

(a) By propagating through seed germination

(b) By propagating through vegetative multiplication

(c) By generating hybrids through intergenetic Pollination

(d) By treating the seeds with gamma radiations

Answer 1

Correct option (b) By propagating through vegetative multiplication

Explanation :

The propagation 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 propagated through seeds, variations creep in due to chance segregation of genes during meiosis and their chance combination during fertilisation.
