Unformatted text preview: BSCI 110B - 2nd Half Patrick Abbot Asst Prof Ecology & Evolution Looking forward: 1) Mendelian inheritance 2) Chromosomes & genetics 3) Microevolution & population genetics 4) Species & speciation 5) Behavior 6) Ecology 7) Communities M endel and the Gene I dea Gr egor M endel (1822-1884) Key concepts 1) Mendel used the scientific approach to identify two _laws of inher itance___ 2) The __Laws of Pr obability__ govern Mendelian inheritance 3) Inheritance patterns are often more complex than predicted by simple Mendelian genetics 4) Many human traits & diseases follow Mendelian patterns of inheritance 5 m Pair of homologous chromosomes Sister chromatids Centromere Pretend you are Gregor Mendel What genetic principles account for the passing of traits from parents to offspring? The _blending_ idea was common at the time of Mendel - idea that genetic material from the two parents blends together (like blue and yellow paint blend to make green) The _Par ticulate_ hypothesis is the idea that parents pass on discrete heritable units (genes) Mendel documented a particulate mechanism through his experiments with garden peas Mendel used the scientific approach to identify two laws of inheritance Mendel discovered the basic principles of heredity by breeding garden PEAS in carefully planned experiments Why peas? Advantages of pea plants for genetic study: Easy to grow Many varieties with well- described characters (such as color) Mating of plants can be controlled Removed stamens fr om pur ple flower Tr ansfer r ed sper m- bear ing pollen fr om stamens of white flower to egg- bear ing car pel of...
