Cross fertilization: stamen (male portion, carpel (female portion, stamen of flowers falls on carpel of same flower, remove anthers (part of stamen) before the, transfer pollen from different flowers to carpel produced pollen had. [fig 14. 2: characters , character- specific property of an organism that is inherited, trait- each variant of a character, choose 7 contrasting pairs of characters [table 14. 1] D. quantitative methods: experimental approach- planned experiments and recorded data, mathematical analysis of results. First scientists to apply quantitative methods to inheritance: true-breeding lines fertilization characteristics/traits, express the same trait generation after generation of self, all individuals in this line are going to express the same. All express same phenotype- appearance of an organism. Tested blending inheritance hypothesis: sperm (fluid inside) + egg (fluid inside) will blend together offspring. (intermediate of both parents: crossed true breeding plants with contrasting traits [fig 14. 3] F1 always resembled one of the parent"s traits.
