- cell division
- meiosis
- gametes are produced from body cells by this cell division
- gametes are formed in the reproductive organs
- gametes have half the number of chormosome
- you get four gametes each with only a single set of chromosome in it
- in the second division they line up again and are pulled apart again
- the two meiotic divisors are known as meiosisI and meiosisII
- produces new cells which only have half the original number of chromosome
- gametes are produced from body cells by this cell division
- mitosis
- it occurs during:
- during growth - to produce more body cells
- during asexual reproduction
- to create replacement cells - when cells are damaged
- the cell has one large pair of chromosome and one small pairs of chromosome
- each chromosome is copied
- when cells divide in two, each cell gets one chromosome
- creating two genetically identical cells
- when cells divide in two, each cell gets one chromosome
- each chromosome is copied
- most organisms have more than two pairs of chromosome
- this type creates identical cells
- it occurs during:
- meiosis
