Genetically diverse offspring result from

Options

A. Mitosis
B. Cloning
C. Dihybridization
D. Sexual reproduction

Answer

To answer the question "Genetically diverse offspring result from," we can break down the reasoning step by step:

### Step-by-Step Solution:

1. **Understanding Gametes**:
- Gametes are the reproductive cells that unite during fertilization. In humans and many organisms, there are two types of gametes: male (sperm) and female (egg).

2. **Formation of Zygote**:
- When a male gamete (sperm) fertilizes a female gamete (egg), a zygote is formed. This zygote is diploid, meaning it contains two sets of chromosomes, one from each parent.

3. **Role of Sexual Reproduction**:
- The process of sexual reproduction involves the combination of genetic material from two parents. This leads to offspring that have a mix of traits from both parents.

4. **Crossing Over**:
- During meiosis (the process that produces gametes), crossing over occurs. This is where homologous chromosomes exchange segments of DNA, leading to new combinations of genes. This genetic recombination contributes to genetic diversity among the offspring.

5. **Conclusion**:
- Therefore, genetically diverse offspring result from sexual reproduction, which includes the processes of gamete formation (via meiosis) and fertilization, as well as crossing over during meiosis.

### Final Answer:
Genetically diverse offspring result from sexual reproduction, which involves the formation of gametes through meiosis and the process of crossing over.
