Study Notes
Mitosis & Meiosis
- Mitosis produces two identical daughter cells.
- Meiosis produces four genetically unique daughter cells.
- Mitosis maintains the chromosome number.
- Meiosis reduces the chromosome number by half.
- Mitosis occurs in somatic cells (body cells).
- Meiosis occurs in germ cells (sex cells).
- Mitosis is for growth and repair. Meiosis is for sexual reproduction.
- In mitosis, parent diploid cells (2n) give rise to two diploid cells (2n)
- In meiosis, parent diploid cells (2n) give rise to four haploid cells (n)
Chromosome Count Examples
- If a parent cell has 24 chromosomes, mitosis will result in daughter cells containing 24 chromosomes.
- If a gamete (sex cell) contains 8 chromosomes, a normal body cell will have 16 chromosomes.
- If a diploid cell has 60 chromosomes, a sperm or egg cell will contain 30 chromosomes.
- A diploid cell with 20 chromosomes will have 40 chromatids in metaphase of mitosis.
- A diploid cell with 20 chromosomes will have 20 chromatids in metaphase I of meiosis.
- A diploid cell with 20 chromosomes will have 20 chromatids in metaphase II of meiosis.
Genetic Variation
- Siblings are genetically different due to crossing over and random assortment during meiosis.
