Common mistake
Misunderstanding Chromosome Pairs
Students often confuse the total number of chromosomes with the number of pairs, stating that humans have 46 chromosomes instead of recognizing they have 23 pairs.
Emphasize that while humans have 46 chromosomes, they are organized into 23 pairs, and clarify the distinction between total chromosomes and pairs.
