Question

(aks 6a) three sources of genetic variation include: a binary fission, mutations, crossing over b mutations, meiosis, mitosis c meiosis, crossing over, mutation d crossing over, mutagens, binary fission

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Binary fission is a form of asexual reproduction that does not contribute to genetic variation (it produces identical offspring), so A is incorrect.
• Option B: Mitosis is cell division for growth/repair and produces identical cells, not a source of genetic variation, so B is incorrect.
• Option C: Meiosis (introduces variation via independent assortment and crossing over), crossing over (exchanges genetic material between homologous chromosomes), and mutation (changes in DNA sequence) are all sources of genetic variation. This matches the requirements.
• Option D: Binary fission is asexual and does not create genetic variation, so D is incorrect.

Answer:

C. Meiosis, crossing over, mutation
