BIOL 211 Lecture Notes - Lecture 8: Gregor Mendel, Blending Inheritance, Gynoecium
Document Summary
We know where information is held in cells (dna), how that information is used to make/modify key molecules of living cells, and importance of those molecules in determining the structure and function of organisms. We know how organisms replicate that dna and distribute it to daughter cells; we know how cell division events fit into reproduction in organisms. Asexual reproduction = mitosis only, offspring are identical to parent. Sexual reproduction = meiosis and fertilization, offspring that are not identical to parents. Character an observable, physical, heritable feature of an organism that varies among individuals (hair color, body height, attached/free earlobes) Trait the specific alternative forms of a character (hair color: brown, red, blond) Problem: traits often have peculiar inheritance patterns: ex: pedigree of a human family, some have brown hair and some have blond. Gregor mendel: austrian monk who studied math and physics.
