Document Summary

10. 1 the beginning of genetics: mendel"s garden peas. Blending theory of inheritance: popular belief which suggested that hereditary traits blend evenly in offspring through mixing of the parents" blood, i. e. like coffee and cream. Mendel studied a variety of heritable characteristics called characters: characters = traits. Mendel established that traits are passed to offspring in the form of discrete hereditary factors which are now known as genes. Mendel observed that rather than blending evenly many parental traits appeared uncharged in offspring, whereas some disappeared in some generations and reappeared in other. 10. 1a mendel chose true-breeding garden peas for his experiment. Mendel chose the garden pea for his research because the plant could be grown easily in the monastery garden. The male gametes are sperm found in the pollen, female gamete found in the carpel. Cross-pollination: pollen to fertilize these flower then had to come from a different plant.
