Mitosis results in two daughter cells identical to the parent cell in terms of genetic material, while meiosis produces four daughter cells with half the number of chromosomes, aiding in gamete formation.
Insights
- Mitosis results in two daughter cells identical to the parent cell in terms of genetic material, maintaining the chromosome number.
- Meiosis produces four daughter cells with half the number of chromosomes compared to the parent cell, crucial for gamete formation.

Recent questions
What is the difference between mitosis and meiosis?
Mitosis results in two identical daughter cells with the same number of chromosomes as the parent cell, while meiosis produces four daughter cells with half the number of chromosomes.
How does mitosis ensure genetic similarity between parent and daughter cells?
Mitosis maintains genetic similarity by dividing the chromosomes equally between two daughter cells, ensuring they have the same genetic material as the parent cell.
What is the purpose of meiosis in cell division?
Meiosis is essential for the formation of gametes by reducing the number of chromosomes in daughter cells, ensuring genetic diversity in offspring.
Why is mitosis referred to as equational cell division?
Mitosis is called equational cell division because it results in daughter cells with the same number of chromosomes as the parent cell, maintaining genetic identity.
How does meiosis contribute to genetic variation?
Meiosis increases genetic variation by producing daughter cells with half the number of chromosomes, allowing for genetic recombination and diversity in offspring.

Cell Division: Equational vs. Reductional Processes
- Mitosis is known as equational cell division because both the parent and daughter cells have the same number of chromosomes and DNA, making them identical. This process results in two daughter cells that are equal to the parent cell in terms of genetic material.
- Meiosis, on the other hand, is referred to as reductional cell division as it halves the number of chromosomes and DNA in the daughter cells compared to the parent cell. This process results in four daughter cells, each with half the number of chromosomes, aiding in the formation of gametes.
