Whose research developed the basic laws of heredity?​

A) ​Gregor Mendel
B) ​Charles Lyell
C) ​Thomas Malthus
D) ​Charles Darwin

Gregor Mendel's research on pea plants in the 19th century led to the discovery of the basic laws of heredity, including the principles of dominant and recessive traits and the idea of genetic traits being inherited independently of each other. Charles Lyell, Thomas Malthus, and Charles Darwin were important figures in the development of the theory of evolution, but their work was not directly related to the study of heredity.
