Note
- In mammals, the only known method of reliably separating X- and Y-bearing spermatozoa in order to produce offspring of a specific sex is flow cytometric sorting. This method is based on the observation that X-chromosome bearing spermatozoa of large farm animals (i.e. cow, sheep, pig and horse) contain 3.5-4.2% more DNA than Y-bearing spermatozoa. In this method relative DNA content is determined by quantitative staining with Hoechst 33342 and DNA content is measured using a modified cell sorter. The major constraint on widespread application of this technique has been the slow sorting rate. In the case of the human, the DNA difference is around 2.8%. Fluorescence in-situ hybridization (FISH) has confirmed sorting accuracy. (Source : INRA)
