alleryA group of plants raised from a single parent plant through vegetative or asexual reproduction is called a:
APureline
BClone
CHybrid
DMutant
Answer & Solution
Correct answer: B. Clone
1. Plants produced asexually from one parent are genetically identical to it.
2. Such a group is defined in the text as a clone, and selecting from them is clonal selection.
3. A pureline arises by self-breeding of a single individual, a hybrid from crossing, and a mutant from a DNA change, so A, C and D are wrong.
4. Hence the answer is B.
