Which of the following is associated with Alfred Sturtevant ?

Options

A. Genetic map
B. Incomplete dominance
C. Linkage
D. Mutation

Answer

To solve the question "Which of the following is associated with Alfred Sturtevant?" we will analyze each option provided:

1. **Genetic Map**: Alfred Sturtevant is known for creating the first genetic map of a chromosome. He developed this map for the fruit fly Drosophila melanogaster in 1923. This is a significant contribution to genetics, as it laid the groundwork for understanding gene locations on chromosomes.

2. **Incomplete Dominance**: This phenomenon refers to a situation where neither allele is dominant, resulting in a blending of traits. It was discovered by the scientist Carl Correns, not Alfred Sturtevant. Therefore, this option is not associated with Sturtevant.

3. **Linkage**: The term "linkage" refers to the tendency of genes located close to each other on a chromosome to be inherited together. This concept was coined by T.H. Morgan, another prominent geneticist. Thus, this option is also not associated with Sturtevant.

4. **Mutation**: Mutations are changes in the genetic material that can occur naturally or be induced. While mutations are a critical concept in genetics, they are not specifically associated with Alfred Sturtevant.

Based on this analysis, the correct answer is:

**Answer: Genetic Map**
