A
haploid cell is a cell that
contains one complete set of chromosomes. Our sex
cells (sperm and eggs) are haploid cells that are produced by meiosis. When sex
cells unite during fertilization, the
haploid cells become a diploid cell. The
haploid number is the number of chromosomes within the nucleus of a cell
that constitutes one complete chromosomal set. This number is commonly
abbreviated as n, where n stands for the number of chromosomes. The haploid
number will be different for different organisms. In humans, the haploid number
is expressed as n=23. Haploid human cells have 1 set of 23 chromosomes.
