H 1 : Blending inheritance characteristics present in parents H 2 : Inheritance of acquired characters traits are modified through use and H 3 : Mendel’s work … II. Garden peas as a model organism A. Heritable variation 1. Studied 7 characteristics… 2 distinct phenotypes of each = what they look like 2. Pure breeding (or true breeding) lines available • purple-flowered parent(s) => all purple-flowered offspring • white-flowered parent(s) => all white-flowered offspring (whatever the hereditary stuff was, these individuals only had one version) B. Breeding system 1. Self-fertilization is normal 2. Mendel could arrange crosses by cutting anthers and performing hand-pollination hybrid = a mix of two types III. Analyzing the inheritance of a single trait A. Flower color: purple x white 1. parentals crossed to yield F 1 offspring, then F 1 s selfed to yield 2. results • Phenotypes of F
