Question

which is required for sexual reproduction?
mitosis
binary fission
diploid cell production
meiosis

Explanation:

Sexual reproduction involves the fusion of gametes (sperm and egg). Gametes are haploid cells produced through meiosis. Mitosis is for growth and repair of somatic cells. Binary fission is a form of asexual reproduction in prokaryotes. Diploid cell production is not directly related to the process of sexual reproduction's requirement for gamete formation. Meiosis reduces the chromosome number by half to form haploid gametes, which is essential for sexual reproduction.

Answer:

meiosis
