named Gregor Mendel is often credited with discovering the principles of Mendelian inheritance in the 19th century. Mendelian inheritance refers to the way genetic traits are passed down from parents to offspring according to specific patterns. Mendel's experiments with pea plants helped him to establish the basic principles of inheritance, including the concepts of dominant and recessive traits, as well as the idea of genetic segregation and independent assortment. These principles laid the foundation for modern genetics and our understanding of how traits are inherited.
