How does the process of meiosis contribute to genetic diversity in sexual reproduction?
Understand the Problem
The question is asking about the mechanisms by which meiosis, a type of cell division that reduces the number of chromosomes in gametes (sex cells), generates genetic diversity. This involves understanding concepts like crossing over, independent assortment, and their impact on offspring.
Answer
Meiosis increases genetic diversity through chromosomal recombination, independent assortment, and the exchange of DNA, creating unique gene combinations.
Meiosis contributes to genetic diversity through chromosomal recombination and independent assortment. During meiosis, DNA is exchanged between paired chromosomes, creating new combinations of genetic material in each daughter cell. This variation is further amplified when gametes from two parents combine during fertilization.

More Information
Genetic diversity is essential for the survival and adaptation of species. It allows populations to respond to changing environmental conditions and reduces the risk of inheriting harmful traits.
Tips
A common mistake is thinking that mitosis, a type of cell division for growth and repair, is responsible for genetic diversity. Mitosis produces identical cells, while meiosis produces genetically different cells for sexual reproduction.
