2. Homologues A pair of chromosomes in which one member of the pair is obtained from the organism's maternal parent and the other from the paternal parentchromosomes found in diploid cellsdiploid commonly referred to as homologous chromosomes

3. Diploid Cells that contain homologous chromosomeshomologous chromosomes The number of chromosomes in the cells is the diploid number and is equal to 2n (n is the number of homologous pairs)

4. Haploid Cells that contain only one member of each homologous pair of chromosomes (haploid number = n)chromosomes At fertilization, two haploid gametes fuse to form a single cell with a diploid number of chromosomesfertilizationgametes

5. Gametes Haploid reproductive cells Haploid Ex: ovum and spermovumsperm

6. Germ Cells Collective term for cells in the reproductive organs of multicellular organisms that divide by meiosis to produce gametesmeiosis

7. Somatic Cells A cell that is NOT or will NOT become a gamete gamete the cells of the body

8. Sexual Reproduction A system of reproduction in which two haploid sex cells (gametes) fuse to produce a diploid zygotehaploidgametesdiploid zygote

9. Zygote Embryo A fertilized egg A diploid cell resulting from fertilization of an egg by a sperm cell
