Which scientist is known for his work on heredity, which complemented the theory of evolution?

Gregor Mendel

Gregor Mendel, an Austrian monk, laid the groundwork for modern genetics through his meticulous experiments on the breeding of pea plants in his monastery garden. Publishing his results in the 1860s, Mendel discovered what we now call the laws of heredity, although his work remained largely unknown until the early 20th century. His principles of gene segregation and independent assortment illuminated the mechanisms of heredity, complementing Darwin's theory of evolution. The rediscovery of his research marked the beginning of the genetic era in biology, highlighting the importance of heredity in evolution.
