The year 1900 was important for generation because of

Options

A. Discovery of gene
B. Discovery of linkage
C. Chromosomal basis of heredity
D. Rediscovery of Mendel's work

Answer

**Step-by-Step Solution:**

1. **Understand the Context of 1900 in Genetics:**
The year 1900 is significant in the field of genetics due to the rediscovery of Gregor Mendel's work on inheritance.

2. **Identify Mendel's Contributions:**
Gregor Mendel, an Austrian monk, conducted experiments on pea plants in the mid-1860s and formulated the foundational principles of inheritance, known as Mendel's Laws.

3. **Recognize the Neglect of Mendel's Work:**
After Mendel published his findings in 1866, his work was largely ignored and forgotten by the scientific community for several decades.

4. **Rediscovery by Scientists:**
In 1900, three scientists—Hugo de Vries, Carl Correns, and Erich von Tschermak—independently rediscovered Mendel's principles and brought them back into scientific discourse.

5. **Impact of Rediscovery:**
The rediscovery of Mendel's work in 1900 marked a pivotal moment in genetics, leading to the establishment of Mendelian inheritance as a key concept in biology.

6. **Conclusion:**
Therefore, the correct answer to the question is that the year 1900 was important for the rediscovery of Mendel's work.

**Final Answer:**
The year 1900 was important for genetics because of the rediscovery of Mendel's work.
