Cytoplasmic inheritance is also called

Options

A. Without sexual reproduction
B. Only female parent takes part in multiplication
C. Most of the cytoplasm of the zygote is provided by ovum
D. All the above

Answer

### Step-by-Step Solution:

1. **Understanding Cytoplasmic Inheritance**:
- Cytoplasmic inheritance refers to the transmission of genetic material that occurs outside the nucleus, primarily through the cytoplasm of the egg (ovum).
- This type of inheritance is often associated with organelles like mitochondria and chloroplasts, which contain their own DNA.

2. **Identifying Alternative Names**:
- Cytoplasmic inheritance is also known by several other terms:
- **Extra-nuclear inheritance**: Refers to inheritance that occurs outside the nucleus.
- **Maternal inheritance**: Indicates that the genetic material is primarily inherited from the mother, as the ovum contributes most of the cytoplasm to the zygote.
- **Non-Mendelian inheritance**: Highlights that this form of inheritance does not follow Mendel's laws of inheritance.
- **Extra-chromosomal inheritance**: Refers to inheritance involving genetic material that is not located on chromosomes.

3. **Evaluating the Options**:
- The question provides several options regarding the nature of cytoplasmic inheritance:
- **Without sexual reproduction**: This is incorrect as cytoplasmic inheritance can occur in both sexual and asexual reproduction.
- **Only female parent takes part in multiplication**: This is misleading; while the ovum contributes most of the cytoplasm, both male and female gametes are involved in reproduction.
- **Most of the cytoplasm of the zygote is provided by the ovum**: This statement is true and accurately describes cytoplasmic inheritance, which is why it is also referred to as maternal inheritance.

4. **Conclusion**:
- The correct answer to the question "Cytoplasmic inheritance is also called" is that it is primarily known as **maternal inheritance**, as it emphasizes the role of the female parent in contributing the cytoplasm to the zygote.
