Mitosis takes place for growth, repair, and in mitosis, a diploid cell produces two haploid cells. The diploid number in humans is 46, the haploid number is 23. Also, in meiosis, cells produced are genetically different.
Diploid = Homogulous pair of chromosomes.
Haploid = One Chromosome.
Stage of meiosis: PMAT
P - Prophase
M - Metaphase
A - Anaphase
T - Telephase.
Homogulous pairs are the same size, shape and carry genes controlling the same characteristic within the same locus.
A cell with pairs of homogulous chromosomes is called a diploid.
A cell with one chromosome from each homogulous pair is a haploid.
Haploid -> Haploid = Mitosis
Diploid -> Diplois = Mitosis
Diploid -> Haploid = Meiosis.
Meiosis increases variability of genes.
Independant segregation causes different combinations in humans. 23 Chromosomes, Two to the power of twenty three different chromosomes = how many different combos there are.
Chemotherapy drugs interfere with metaphase, mess up spindle formation.
