Document Summary
Artificial selection was one of the first tools used - applied genetics (10k years ago) Valuable herds of animals to make life easier. Used also with plants for a variety of beneficial reasons. Selective breeding produce sheep that made large quantities of wool. Dilemma: ram with good wool, but lost in offspring - can"t predict heritability. Ram is only worth its wool, meat, and skin. One parent contributes more to an offspring"s inherited traits (uniparental inheritance) Aristotle: contended that human was already inside a sperm. Traits of parents are blended into of offspring - forever changed. Still missing explanation for siblings or next gen - good for individual offspring. Presided over augustinian monastery in brunn (present day brno, czech republic) Proposed that breeders could improve predictability of traits if asking. Entered augustinian monastery at 21, sent by napp to university of vienna. Studied physics with doppler, maths, chem, botany, plant physio.
