What is the importance of meiosis?
Understand the Problem
The question is asking about the significance of meiosis, which is a type of cell division that reduces the chromosome number by half, leading to the formation of gametes. It is crucial for sexual reproduction and contributes to genetic diversity through processes such as crossing over and independent assortment.
Answer
Meiosis ensures the correct number of chromosomes in offspring and promotes genetic variation.
The final answer is that meiosis ensures organisms produced via sexual reproduction have the correct number of chromosomes and promotes genetic variation through recombination.

More Information
Meiosis is crucial for sexual reproduction because it reduces the chromosome number by half, resulting in haploid gametes. This ensures that when gametes fuse during fertilization, the offspring have a complete set of chromosomes. Additionally, meiosis introduces genetic variation through independent assortment and crossing over.
Tips
A common mistake is confusing meiosis with mitosis. Meiosis leads to genetic variation and halving of chromosome numbers, while mitosis results in identical daughter cells.
