Study Notes
Meiosis and Genetic Variation
- Meiosis produces haploid cells for sexual reproduction
- These haploid cells are genetically unique, increasing variation in offspring.
Mechanisms for Genetic Variation
- Crossing over between non-sister chromatids during prophase I.
- Random assortment of homologous chromosomes during metaphase I.
- Fusion of gametes from different parents.
Outcome of Genetic Variation
- Improved survival prospects for a species, promoting biodiversity.
