In which mode of inheritance do you expect more maternal influence among the offspring?

Options

A. Autosomial
B. Cytoplasmic
C. Y-linked
D. X-linked

Explanation

**Step-by-Step Solution:**

1. **Understanding Modes of Inheritance**:
- There are various modes of inheritance, including autosomal, X-linked, and cytoplasmic inheritance. Each of these modes has different implications for how traits are passed from parents to offspring.

2. **Defining Cytoplasmic Inheritance**:
- Cytoplasmic inheritance, also known as maternal inheritance, refers to the transmission of genetic material that is located outside the nucleus, specifically in the cytoplasm of the egg cell. This includes genes found in organelles like mitochondria and chloroplasts.

3. **Maternal Influence in Cytoplasmic Inheritance**:
- In cytoplasmic inheritance, the offspring inherit the cytoplasmic traits exclusively from the mother. This means that any traits associated with the cytoplasmic genes will show a strong maternal influence, as the father contributes little to no cytoplasmic genetic material.

4. **Comparison with Other Modes**:
- In contrast, autosomal inheritance involves genes located on autosomes (non-sex chromosomes) and can be influenced by both parents equally.
- X-linked inheritance involves genes located on the X chromosome, where the mother can pass on X-linked traits to both sons and daughters, but the influence is not as exclusively maternal as in cytoplasmic inheritance.

5. **Conclusion**:
- Therefore, the mode of inheritance that exhibits the most maternal influence among the offspring is **cytoplasmic inheritance**.

**Final Answer**: Cytoplasmic inheritance.
