Lecture 4: Mendelian Inheritance I. How does inheritance work? A. Ancient Greeks ● Pangenesis i. Particles of man and woman blend together ii. Each body part has different particle (pangenes) B. Homunculus theory ● Preformed adult in a sperm ● Male “planted” homunculus in female ● Theory disproved, controversial C. Blending Inheritance ● Form of inheritance in which features of offspring are the average of those seen in parents i. If blending continued, everyone would ...
