Chromosomes are made from DNA. Genes are short sections of DNA.
Mitosis is the type of cell division that leads to growth or repair. When a cell divides by mitosis:
- two new cells form
- each cell is identical to the other one, and the cell they were formed from
Meiosis- Gametes are formed from cells in the reproductive organs.
In meiosis, during sexual reproduction it allows the child the same number of genes as their parent.
It helps generate variation through the crossing over of chromosomes and more mutations.
