BIOL1003 Lecture Notes - Lecture 1: Meiosis, Pangenesis, Aneuploidy
Document Summary
Uses of genetics: disease diagnosis + cure. Jewish law for mothers not to circumcise third boy if two die from it. Rh (blood type) incompatibility: crop stock and improvement. Now genetic markers, fingerprinting, gmos: forensics. Paternity/ identity testing: conservation importance of genetic diversity. Cheetahs lost most diversity in last ice age. Warning ex: royal families, domesticated animals: systematics. Well choses morphological traits can be good. Dividing cells scramble their parts + put back together. Nucleus breaks up to form dark, easily stainable bodies. Hypothesized a factor that conveys traits from parent to offspring. Gene fundamental physical + functional unit of heredity. Observation of cell division, chromosomal band and correlation to inherited traits. No idea what chromosomes were made out of. * condensed form of protein + nucleic acids carrying genetic info, visible only during cell division. * when not dividing spread out and relaxed. Chromatin still made of proteins + nucleic acids centromere telomers.
