Haploid representation is symbolized by which notation?

• A. n
• B. 2n
• C. 3n
• D. 4n

Answer: (A)

Haploid means one complete set of chromosomes, which is denoted by n. In contrast, most body (somatic) cells have two sets (2n). Gametes carry just one set, so their chromosome number is n, and when two gametes fuse, a diploid zygote with 2n is formed. Triploid or tetraploid states (3n, 4n) exist in some contexts, but they are not haploid. Therefore, the haploid notation is n.
