Chromosome maps/genetic maps were first prepared by

Options

A. Sutton and Boveri (1902)
B. Bateson and punnett (1906)
C. Morgan (1910)
D. Sturtevant (1911)

Explanation

To answer the question "Chromosome maps/genetic maps were first prepared by," we can follow these steps:

### Step 1: Understand the Concept of Chromosome Maps
Chromosome maps, also known as genetic maps or linkage maps, are graphical representations that show the arrangement of genes on a chromosome and the distances between them. These maps help in understanding the genetic linkage and inheritance patterns.

**Hint:** Remember that chromosome maps are crucial for studying genetic traits and their inheritance.

### Step 2: Identify the Key Contributors
The question provides several options:
- A) Jeton and Bode
- B) Bateson and Punnett
- C) Chilsey and Morgan
- D) Strudvand

**Hint:** Look for historical figures known for their work in genetics and chromosome mapping.

### Step 3: Research Historical Context
The first chromosome maps were created in the early 20th century. The pioneer in this field was Strudvand, who worked on the fruit fly Drosophila. He created the first chromosome map in 1911 and expanded it in 1913.

**Hint:** Focus on the timeline of genetic research and the contributions of early geneticists.

### Step 4: Confirm the Correct Answer
Based on the information gathered, Strudvand is recognized for creating the first chromosome map. Therefore, the correct answer to the question is option D) Strudvand.

**Hint:** Always verify the contributions of scientists to ensure the accuracy of your answer.

### Final Answer
The chromosome maps/genetic maps were first prepared by **Strudvand** (Option D).
