Document Summary

Bioc15fall2013 lecture 16: population genetics and lecture 17: hardy-weinberg equilibrium. Tobiano phenotype with a snp of kit and an inversion. More than one band = organism is heterozygous. Imaginary example w/ physical markers: o/o or o/o gives black eyes aliens, oo = orange eyes, o/o x o/o black eyes (all o/o, o/o x o/o o/o or o/o (black eyes or orange eyes) 1: having 10 str = black eyes, having o and 6 str = orange eyes the region of 6 str is a marker for the orange eye colour. In 1928 muller devised a method of searching for any lethal mutation on the x-chromosome (chromosome 1 in. Drosophila: constructed chromosome called c1b which carries and inversion cross over suppressor (c no recombinations), a lethal (l) and a dominant mutation bar-eye (b) marker. 3: where the loop is = no crossing over.
