Haploid cells describe which statement?

• A. Have one complete set of chromosomes.
• B. Have two complete sets of chromosomes.
• C. Have four sets of chromosomes.
• D. Have partially duplicated chromosomes.

Answer: (A)

Haploid means a cell has a single complete set of chromosomes (one copy of each chromosome type, n). In humans, this is 23 chromosomes in gametes, produced by meiosis to halve the chromosome number. This is why having two complete sets (diploid) or four sets (tetraploid) doesn’t describe haploid, and partially duplicated chromosomes isn’t the defining idea. So the statement that a haploid cell has one complete set of chromosomes best fits.
