BIO 181 Lecture 2.2

Lecture 2.2: Mendel’s Principle of Segregation

Overview

In the previous lecture, we outlined Mendel’s observations. But if that’s all Mendel did, very few people would have ever heard of him, whereas today he is rightfully one of the most famous scientists in history. Here we see why—he explained what he saw correctly. That explanation, often misinterpreted today as an expression of modern genetics, set us on the course to understand heredity and variation among organisms.
