[biology notes: lecture 12 (pg 211- 230] 1. If you roll two dice together, what is that chance of rolling double 4s? (1/6)(1/6)=(1/36) In his work with peas mendel studied a variety of heritable characteristics he called characters (flower colour, seed shape) A variation in character is called a trait (white or purple flower) Characters are passed to offspring in the form of discrete hereditary factors (genes) Mendel"s most important innovation was his quantitative approach to science. 10. 1a mendel chose true- breeding garden peas for his experiment. The female gametes are egg cells produced in the carpet of the flowers. Female gametes are egg cells produced in the carpel of the flowers. Normally pea plants self- fertilize but mendel prevented self- fertilization by cutting off the anthers. Pollen had to come from a different plant (cross pollination) !0. 1b mendel first worked with single character crosses. Flower colour was one of the seven characters that mendel selected for.
