Also i need to know how many choromosomes and chromosome pairs the Parent cell has before undergoing meiosis.How many chromosomes and chromosome pairs does the Parent cell have before undergoing mitosis?
If we are talking about humans, then all cells except the sex cells (and the red blood cells that lose their nuclei) have 46 chromosomes or 23 pairs. That is written as 2N=46, N=23. Mitosis is a process where you start with one cell, and end with two, and the two new cells have the same types and numbers of chromosomes than the original cell.
Meiosis is a different process, where you start with 46 chromosomes and 23 pairs, and end up with cells (gametes) with 23 chromosomes and one chromosome from each pair.
