How did Gregor Mendel's research affect the science of his time?
Rufina [12.5K]

Answer:

The correct option is A. His research was not appreciated by the scientific community until after he died.

Explanation:

Gregor Mendel was an Austrian monk who laid the foundation of genetics. Mendel studies seven traits from the pea plants and formed the law of segregation and law of independent assortment.

The work of Mendel was not appreciated until his death. In the 20th century, his work was eventually rediscovered and appreciated.
