Document Summary
Brief history will come out: mini adult already in the egg and this is what people thought for a. Preformationist people imagines that there is just a small person and they. Epigenesis not a preformed mini adult in the reproductive cells but a series. Wasn"t until the early (cid:884)(cid:882)th century that they started looking at this of chemical reactions that occurred in the cell: saw that chromosomes were important. Thomas morgan: found that color and shapes were inherited, genes (units that contain traits, which is all they knew at the time) is. Human genome project: 22,000 genes, (umans don"t have as many genes as we thought we had, so these are many questions that arose. Epigenetic traits: cells that conserve patterns of gene expression that result from changes in the chromatin without changes in the dna sequence. During presentations explains that the mechanisms they are trying to target and the mechanisms and the methods to get to the mechanism.
