Study Notes
Sexual and Asexual Reproduction
- Meiosis is the formation of four non-identical cells from one cell.
- Mitosis is the formation of two identical cells from one cell.
Sexual Reproduction
- Involves the joining of male and female gametes, each containing genetic information from the mother or father.
- Examples: sperm and egg cells in animals, pollen and egg cells in flowering plants.
- Gametes are formed by meiosis, making them non-identical.
- A normal cell has 46 chromosomes, with two sets (23 pairs) of chromosomes.
- Each gamete has 23 chromosomes and they fuse in fertilization, mixing genetic information from each parent.
- This leads to variation in the offspring.
Asexual Reproduction
- Involves one parent with no gametes joining.
- Happens using the process of mitosis, forming two identical cells from one cell.
- No mixing of genetic information occurs.
- Leads to clones, which are genetically identical to each other and the parent.
- Examples: bacteria, some plants, and some animals.
Meiosis
- Formation of four non-identical cells from one cell.
- Cells in the reproductive organs divide by meiosis to form gametes.
- Gametes only have one copy of each chromosome.
- The cell makes copies of its chromosomes, resulting in double the amount of genetic information.
