1. Human sperm cells and egg cells are (2 points)
diploid, each containing 23 chromosomes.
diploid, each containing 46 chromosomes.
haploid, each containing 23 chromosomes.
haploid, each containing 46 chromosomes.
The sperm cells and egg cells in humans each contain the haploid chromosome number (each containing 23 chromosomes). This is the case so that when the two gametes fuse the restore the diploid number but individually they are haploid.
