I mean like the X loss mosaics in Drosophila melanogaster gynandromorphs? If it was a chromosome other than the X that was lost at the first cell division one would get a bilateral mosaic if the chromosomes in question were heterozyous for the colour markers and the one bearing the dominant alleles were lost. If it were the X, one would expect the sex to be also split. Dave Baillie Professor IMBB Simon Fraser University Burnaby, BC, Canada .
