Unformatted text preview: How is genetic information transmitted through sexual reproduction? Why was Mendel successful? How are genes inherited? Individual genes - one factor crosses or monohybrid Two or more independently assorting genes Dyhbrid crosses Human pedigree analysis Can Mendels rules explain and predict the inheritance of genes that dont show simple Mendelian behaviors? codominance or partial dominance sex-linkage probabilities Why was Mendel successful? What did he do right? He was lucky He kept to a simple and well defined system One trait at a time 2 traits at a time Well defined traits depend on only one gene Model system: fast growing(short generation time) Looked at multiple generation Individual plants lots of progeny Self cross Fig. 14-3-3 Mendels experiments in hybridization P Generation (true-breeding parents) F 1 Generation Fig. 14-3-3 Mendels experiments in hybridization P Generation (true-breeding parents) F 1 Generation (hybrids) F 2 Generation 705 224 Does the behavior of chromosomes in meiosis explain Mendels results? Chromosome segregation through meiosis Try this flash animation, available on T-square: MeioticSegregation.html You have white and purple flowered pea plants in your garden. Propose a genetic cross (breeding expt) to determine whether a particular purple-flowered pea plant is homozygous or heterozygous. homozygous or heterozygous....
