Alfred Sturtevant is associated with

Options

A. Cytoplasmic inheritance
B. Linkage theory
C. Chromosomal Theory of Inheritance
D. Genetic map

Answer

To solve the question regarding Alfred Sturtevant's association, we can follow these steps:

### Step 1: Understand the options provided
The question presents four options related to inheritance and genetics:
- A) Cytoplasmic inheritance
- B) Linkage theory
- C) Chromosomal theory of inheritance
- D) Genetic map

### Step 2: Analyze each option
- **Cytoplasmic inheritance**: This concept is primarily associated with the work of Correns, who studied inheritance patterns in plants.
- **Linkage theory**: This theory is associated with Thomas Hunt Morgan, who conducted experiments with fruit flies (Drosophila) to understand how genes are inherited together.
- **Chromosomal theory of inheritance**: This theory was also developed by Thomas Hunt Morgan and his students, explaining how genes are located on chromosomes.
- **Genetic map**: This is a representation of the arrangement of genes on a chromosome, and it is specifically associated with Alfred Sturtevant, who created the first genetic map.

### Step 3: Identify the correct association
From the analysis, we can conclude that Alfred Sturtevant is associated with the **genetic map**.

### Final Answer
The correct answer is **D) Genetic map**.
