q-arm p-arm Replicated Chromosomes – identical DNA on sister chromatids which are connected at the centromere Unreplicated Chromosome Locus – physical location of a gene on a chromosome Ploidy level = # of versions of each chromosome Haploid = 1 version – bacteria, some male insects
Identical Particles. We would like to move from the quantum theory of hydrogen to that for the rest of the periodic table One electron atom to multielectron atoms This is complicated by the interaction of the electrons with each other and by the fact that the electrons are identical
Identical Particles. In quantum mechanics two electrons cannot be distinguished from each other students have names and can be ‘tagged’ and hence are distinguishable a system of two particles has a wave function that depends on the positions of both particles (x 1 ,x 2 )
Identical Twins. Identical twins do show remarkable similarities, but only in characteristics you would expect: intelligence, temperament, gestures, posture and pace of speech. However, environment plays a big role too. increase in age = greater difference in personality
