Document Summary

Thursday, 16 october 2014: monk, gardener, statistician, described a mechanism for inheritance other than blending . How plants make seeds: pollen (aka male gpt, ovules (aka female gpt) True breeding lines: plants that always produce progeny that look just like themselves (for some characteristic) The value of quanti cation: a statistical approach to biology. Pea plants resemble their parents: e. g. ower color, (white x white) yields white always, (purple x purple) yields purple usually sometimes got white color. Called the white owers hybrids ( striking regularity : mendel"s inheritance hypothesis. Gene vs. allele: gene: nucleotide sequence that is associate with one (or more) trait(s) in an organism. E. g. ower color: allele: one (or more) variant(s) of a gene, associated with a speci c form of the trait. Genotype vs. phenotype: genotype: full complement of alleles possessed by an organism for one (or more) trait(s)
