Human eggs and sperm carry one set of chromosomes, so they are:
ADiploid cells
BTriploid cells
CMultiploid cells
DHaploid cells
Answer & Solution
Correct answer: D. Haploid cells
1. Sex cells must halve the chromosome number so fertilisation restores it.
2. Human cells that contain one set of chromosomes are called gametes, or sex cells.
3. These are eggs and sperm, and are designated 1n, or haploid.
4. A diploid cell would double the count at every generation.
