Document Summary
Gene- determine characteristics (part of chromosome that gets converted into. Locus- location of a gene on a chromosome. The homunculus theory: sperm donates an entire copy of itself to offspring and egg only provides nutrients. (problem, offspring looking like both parents or more like their mom) The blended theory: sperm and egg contain essential essences that mix together (problem: siblings don"t all look alike) Good things about peas: variation, noticeable differences, easy to grow, easy access to reproductive parts) Selfing: transfer of pollen to stigma within the same plant. Mendel"s way is cross-pollination (forced mating by taking pollen of one plant and transferring it into another) Cross- mating between 2 individuals resulting in fusion of gametes. Diploid- 2 homologous sets of chromosomes in eukaryotic cells. F1 generation- progeny of mating of p generation. F2 generation- offspring of mating of f1 generation. Monohybrid crosses is the mating between individuals who have different alleles at one genetic locus of interest.
