Document Summary
Peer tutoring, must have gotten an a or an a- in the class, must have taken the course at. Genetic mapping ii: centromere mapping wt tetrads, chi square in linkage analysis physical vs recombinant maps in breeding, often trying to introduce as single trait into a line, not other traits. (ex: disease resistance) Might take 15-20 generations to keep on crossing over and over again, but if you have markers on either side, you can speed up the process. This use of markers on the side is a multi-million dollar industry these days. Takes a long time to build up maps, so want to do it with multiple traits. Drosophila wt vermillion eyes (v), cv (cross veinless wings) ct (cut wings ) Your working wt a second parent who doesnt mask the gamete type. The evidence of linkage would be more parental type gametes than recombinant. And we do have an abundance of parent type, suggesting evidence of linkage.
