Notice that diploid cells
which 18 are the complete number of chromosome pair of the organism. This usually
happens under cell divison –mitosis which process of replicating oneself to
produce another like cell. Meiosis occurs in gametes, sex cells. Their respectively
called spermatogenesis (sperm cells) and oogenesis (egg cells). These cell
division –meiosis produces haploid cells, in which in words “half” from the
complete cell chromosome number, hence, these haploid cells only produce half number
or one set of chromosome (9) instead of the complete pair which in this case,
18.
