Meiosis produces genetically varied cells due to crossing over and independent assortment, not identical ones.
Ref: NCERT Class 11 Biology Chapter 10: Cell Cycle and Cell Division Meiosis - Meiosis II and Significance - Genetic Variability
Meiosis consists of two divisions (meiosis I and II) and produces haploid cells, contributing to genetic variation.
