Markers for the Y Chromosome of , and Their Use in Studying Pollen Tube Growth Rates which were not sex linked by pooling 18 females into one sample and 18 males into another (For the method, see Michelmore, et al. submitted). Differences between the two samples would presumably relate to the Y chromosome. DNA was extracted from the two samples and subjected to polymerase chain rea
