alleryAn organism whose somatic cells contain more than two complete sets of chromosomes is said to be:
APolyploid
BDiploid
CHaploid
DA mutant
Answer & Solution
Correct answer: A. Polyploid
1. Diploid (2n) cells have two chromosome sets and haploid (n) gametes have one.
2. Having more than two sets is termed polyploid, and the condition polyploidy.
3. A mutant simply carries an altered DNA sequence, which is a different concept, so option D is a trap.
4. Hence the answer is A.
