A 200 kg of vegetative tissue propagates 100 plants by cuttings. If the parent had a mutation rate of 0.01% per generation, what is the expected genetic similarity of the offspring?
AAround 50%
BAround 75%
CEffectively 100% identical to the parent
DLess than 25% (option)
Answer & Solution
Correct answer: C. Effectively 100% identical to the parent
1. Vegetative propagation copies the parent DNA mitotically.
2. No meiosis, no recombination, no fusion of gametes occurs.
3. Mutation rates this low do not change the population-level similarity, which remains effectively identical.
