Document Summary
October 12: background, monk, basic rules in inheritance in eukaryotes, 1865- published, 1900 people appreciated it ii. Experimental organism: garden pea- piguin satium, advantages: 1: many varieties, easy to grow- short genetic time. Identifiable traits: flowers, stamen-male, carpel- female, self-fertilize, cross fertilization, remove anthers (part of stamen) before pollen was produced, transfer pollen from different plants/flowers to carpel (fig 14. 2) ii. Characters: characters- specific property of an organism that is inherited, trait- each variant of a character, seven contrasting pairs of characters, table 14. 1. Yellow vs green: quantitative methods, experimental approach, mathematical analysis iv. Sex=haploid: tested blending inheritance hypothesis i. ii. Sperm fluid and egg fluid: offspring intermediate. Crossed true breeding plants with contrasting traits: p= parental generation, f1= first filial generation, f2= second filial generation (fig 14. 3, observations, f1 always resembled one of the parents trait that disappeared in f1 often reappeared in f2, conclusions. If fluids blended, difficult to explain how they could separate blending hypothesis rejected ii.
