Control of mammalian sex ratio by sexing sperm**Work performed under the auspices of the U.S. Department of Energy by the Lawrence Livermore National Laboratory under contract no. W-7405-ENG-48.

摘要: Preselection of sex is discussed with emphasis on methods which have claimed success in separating X- and Y-chromosome-bearing sperm. Much the recent experimental work human X Y sperm judges enrichment solely by staining for a quinacrine dye, causes bright fluorescence long arm chromosome. This method questioned because endpoint may be producing spurious results. Flow sorting believed to first verified separation mammalian sperm, but were nonviable. cytometry can used quickly determine other techniques. Bulk separation, as contrasted based determination individual characteristics, 80% seems reasonable future goal.
