Academy video or online resources)

SEXUAL REPRODUCTION OVERVIEW
Diploid (2n) - contains 2 sets of
chromosomes, one set inherited
from each parent. Body cells
are diploid cells.
Haploid (n) - contains 1 set of chromosomes.
Sex cells (gametes) are haploid
cells.
Meiosis—type of cell division that forms sex
cells (gametes). Meiosis
reduces the chromosome
number by half.
Ovaries—location of meiosis in females.
Testes—location of meiosis in males.
Egg—female sex cell (gamete).
Sperm—male sex cell (gamete).
Fertilization—joining of an egg and a sperm
cell.
Zygote—a fertilized egg.
Mitosis- type of cell division that produces
diploid body cells.
HUMAN diploid (2n) number is ________.
HUMAN haploid (n) number is ________.
