The scientist who first discovered cytoplasmic inheritance was

Options

A. Correns
B. Rhoades
C. Mendel
D. Morgan

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks for the scientist who first discovered cytoplasmic inheritance. Cytoplasmic inheritance refers to the transmission of genetic material that is located outside the nucleus, primarily in the cytoplasm of the cell.

2. **Reviewing the Options**: The options provided are:
- A) Corens
- B) Rodis
- C) Mendel
- D) Morgan

3. **Analyzing Each Option**:
- **Option A: Corens**: Corens is known for his work on cytoplasmic inheritance. He studied this phenomenon in the plant *Mirabilis jalapa*, which is a key example of cytoplasmic inheritance.
- **Option B: Rodis**: Rodis is associated with studies on male sterility in maize but did not discover cytoplasmic inheritance.
- **Option C: Mendel**: Mendel is known as the father of genetics and is famous for his laws of inheritance, but his work focused on nuclear genetics, not cytoplasmic inheritance.
- **Option D: Morgan**: Morgan is recognized for his research on linkage and recombination in *Drosophila melanogaster*, which does not pertain to cytoplasmic inheritance.

4. **Conclusion**: Based on the analysis, the correct answer is **Option A: Corens**, as he was the first scientist to discover cytoplasmic inheritance through his studies on *Mirabilis jalapa*.

**Final Answer**: The scientist who first discovered cytoplasmic inheritance was Corens.
