Biology for IGCSE & O level - Variation And Selection (Section 5 - No. 10)
What is the role of meiosis in the context of variation?
Meiosis reduces the number of chromosomes to create gametes, contributing to genetic variation through shuffling of genes.
Meiosis duplicates DNA before cell division, preventing any variation.
Meiosis repairs mutations that may arise during DNA replication.
Meiosis ensures identical genes are passed to each offspring.
Explanation
Meiosis produces gametes with half the number of chromosomes and shuffles genetic information during the process, leading to genetic variation.
