Document Summary
Results not blended colour, inherited either yellow (75%) or green (25%) Recessive: hidden (expressed only if both parents contribute it) Law of segregation of inheritable characteristics: inheritance, particulate in nature (inherit a discrete trait), not blending or mixing. Gene: did not formulate gene as a basic unit of inheritance (close to it) Reformulation of biology: rediscover laws of heredity (3 botanists independently) . 1990: published results of their experiments, which supported mendel"s work . George simpson (1930"s): formulates new synthetic theory (combines evolution and genetics) . Nucleus: chromosomes stored (dna and rna) nucleus and cytoplasm . Chromosomes (1953): watson and crick discovered way to photograph into a cell and see structure of dna . Humans: 46 strands, 23 pairs of chromosomes in every cell . Base pairs: adenine and thymine, cytosine and guanine . Dna (genetic) code: sequence of molecules on chromosome strands that are matched up together (base pairs, sugars and phosphates) .
