### Question on Sexual Reproduction

**Sexual reproduction requires which of the following?**

- love & tenderness
- independent assortment & homozygosity
- **mitosis & epistasis** (selected)
- meiosis & fertilization

*Note:* The correct answer for the process of sexual reproduction should involve meiosis and fertilization, not mitosis and epistasis.

---

**Explanation of Options:**

1. **Love & tenderness**: While these are important aspects of social and emotional relationships, they are not biological requirements for sexual reproduction.
2. **Independent assortment & homozygosity**: Independent assortment is a key principle of genetics that occurs during meiosis, but homozygosity refers to having identical alleles for a gene, which is not a requirement of the sexual reproduction process itself.
3. **Mitosis & epistasis**: Mitosis is the process of cell division that results in two daughter cells, not directly involved in sexual reproduction. Epistasis refers to the effect of one gene being dependent on the presence of one or more 'modifier genes.' These terms are not directly associated with the fundamental process of sexual reproduction.
4. **Meiosis & fertilization**: Meiosis is the cell division process that reduces the chromosome number by half, creating gametes (sperm and egg cells), and fertilization is the fusion of two gametes to form a zygote, which are the essential steps in sexual reproduction.

This question addresses important concepts in biology. Understanding the correct processes involved in sexual reproduction is critical for students learning about genetics and cell biology.
