6. Key Terms Haploid Cells: Diploid Cells: Somatic Cells: Gametes:
Fertilization
Zygote

7. Karyotypes:
and Homologous Chromosomes (pairs):

9. Comparison of Reproduction with Cell Divisions
MITOSIS
MEIOSIS
ASEXUAL
Makes Body cells (somatic)
1 cell 2 cells
1 division
Genetically identical Cells (clones)
Diploid cell  Diploid
SEXUAL
Makes Sex cells (gametes)
1 cell 4 cells
2 divisions
Genetically Diverse (4 dif sperm/eggs)
Diploid cell  Haploid
