Document Summary
15 (pg 343-354, 363-371): *no detailed study; key terms + concepts. Blending inheritance: parents make equal genetic contributions to their offspring; their genetic material blends together as it is passed to the next generation. Particulate inheritance: determinants of hereditary traits are transmitted intact from one generation to the next. Inheritance patterns hybridization: 2 individuals w/ different characteristics mated to each other--> offspring are hybrids. Mendel chose peas b/c: there were readily available varieties that differed in phenotype; each trait had 2 variants (tall or short, red or white, etc, they"re self-fertilizing: female gamete fertilized by male gamete from the same plant. Useful for producing plants that breed true for a given trait (trait is consistent across generations)--> true-breeding line: it was easy to make crosses. Flowers were easy to manipulate and cross-fertilize for hybridization. Ideas regarding properties + transmission of traits from parents to offspring: dominant + recessive traits.
