Cells that have pairs of every chromosome are called______________ while cells that have one copy of a chromosome are called____________________?

• complete, incomplete

• multiploid, monoploid

• diploid, haploid

• megaploid, uniploid

Most human cells have 46 chromosomes (23 pairs). If egg and sperm cells each had this number of chromosomes when they combine during fertilization there would be problems. Therefore, egg and sperm cells have _______________________.

• half the amount of chromosomes as compared to other cells.

• twice the amount of chromosomes when compared to other cells.

• four times the amount of chromosomes when compared to other cells.

• a quarter of the amount of chromosomes when compared to other cells.

Another name for sex cells, like egg and sperm, is ____________________

• oocytes

• chromoblasts

• fertilization

• gametes
