 Gametes – sex cells  Gametes fuse  fertilization  zygote  Gametes are formed by meiosis  Somatic cells – all other cells but sexual cells  Every.
Meiosis “Reduction Division”. Reduce the number of chromosomes by half Produce haploid cells (1 set of chromosomes) 2N → N Produce gametes (egg or sperm)
Meiosis Cell division in sex cells that produces gametes containing half the number of chromosomes as a parent’s body cells (somatic cells)

Introduction to Meiosis. Diploid Diploid is what a cell is called when it has both copies (2N) of each chromosome (N). The diploid number is abbreviated.
Meiosis. Meiosis is a form of cell division where diploid body cells make haploid gametes. In humans, this means cells that have 46 chromosomes (2N) divide.
