Study Notes

Meiosis

Meiosis is a cell division process that occurs in reproductive organs (testes and ovaries in humans)
It produces gametes (sperm and egg cells)
It is a reduction division, reducing the number of chromosomes from diploid to haploid
A diploid cell divides twice to create 4 haploid cells, which are genetically different
The purpose of meiosis is sexual reproduction
It is fundamental in passing genetic information from parent to offspring, while also creating genetic diversity in future generations.
