Chapter 14 Mendel and the Gene Idea Lecture Outline Overview: Drawing from the Deck of Genes The ?blending? hypothesis popular 1800s This hypothesis proposes that genetic material contributed by each parent mixes in a manner analogous to the way blue and yellow paints blend to make green. With blending inheritance, a freely mating population will eventually give rise to a uniform population of individuals. Everyday observations and the results of breeding experiments tell us that heritable traits do not blend to become uniform. An alternative model: the ?particulate? inheritance proposes that parents pass on discrete heritable units, genes, that retain their separate identities in offspring. Genes can be sorted and passed on, generation after generation, in undiluted form.

Gregor Mendel Studied traits that occur in distinct forms. Developed true-breeding varieties When bred amongst themselves these plants produced offspring identical to the parent for that trait. Used mathematical analysis in his studies. Definitions Gametes: reproductive cells produced by sexually reproducing organisms. Two types: male gametes = sperm In plants: contained in pollen Female gametes = eggs In plants: contained in ovules which mature to seeds when fertilized Ovules contained in carpels Fertilization Fertilization: fusion of egg and sperm Self-fertilized: fusion of sperm and egg from same plant Cross fertilized: fusion of egg and sperm from two different plants Produced hybrids F1: first generation F2: second generation Mendel?s Model
