Reminder: Test on Friday.
Note: 2N: Diploid Cell (N= the number of different chromosomes)
Meiotic Differences Between
Men
Spermatogonium :Cells that line the insides of Seminiferous tubules in the testis. 2N
Mitosis
1Degree (1st Division) Spermatocyte 2N
Meiosis 1
2 Degree (2nd Division) Spermatocytes N N
Meiosis 2
4 Unique Sperm NNNN
Lasts from puberty to death.
Women
Embryonic Oogonium 2N
Mitosis
1 Degree (1 Division) Oocytes 2N 2N
Stays in Prophase 1
Puberty Meiosis 1
2 Degree (2 Division) Oocyte: This is the cell that is ovulated. This is also the cell that is fertilized N Polar Body
The N cell produced from the female has a too much genetic information soonly when the cell is fertilized, Mitosis 2 occurs, then the chromosomes from the nucleus of the sperm cell form the zygote.
