BIO206H5 Chapter Notes - Chapter 14: Mendelian Inheritance, Franz Unger, Christian Doppler
Document Summary
The blending hypothesis suggests that the genetic material contributed by the two parents mixes in an analogous way to the blending of blue and yellow making green. This hypothesis predicts that over a period of time two parents will give rise to a population of individuals with similar characteristics. However, we have information that prove this hypothesis wrong; also, the blending hypothesis fails to explain why traits skip generations and then reappear later on. The gene idea is an alternative; proposes that parents pass on discrete heritable genes that have separate identities in their offspring. Therefore, genes are like a deck of cards, shuffled, passed along randomly, gen after gen. Christian doppler and franz unger aroused mendel"s interest in plants. Mendel worked with peas because they had a high variety rate, short gen time, and the large number of offspring generated with each mating.
