In 1866, the world was a different place...Gregor Mendel was anAustrian monk and theson of a farmer. He wasfamiliar with the conceptof breeding, or crossingadult organisms toachieve a desired look inthe offspring.http://www.mpiz-koeln.mpg.de/~stueber/mendel/mendel.jpg• He also usedhis knowledgeof statisticsandmathematics todeduce thefundamentalprinciples ofgeneticsSome traits were obviously inherited –but how?Mendel wanted to understand howtraits were passed from onegeneration to another. So he chosepeas, which have a number of veryhandy characteristics.http://www.mpiz-koeln.mpg.de/~stueber/mendel/mendel.jpghttp://www.blc.arizona.edu/courses/181gh/rick/genetics1/graphics/pea_traits.gif2
