The clones are assayed for autosomal meiotic nondisjunction by crossing clone-bearing females to males that carry a compound autosome (C(3)EN to screen 2L and C(2)EN to screen 3R).
[2,3,8] Miscellaneous chromosomal abnormalities have been demonstrated in some but not all affected individuals and are currently classified into 2 groups[3,9]: (1) various mosaicism for almost any autosome or sex chromosomes and (2) nonmosaic balanced X;autosome translocations with breakpoints in the juxtacentromeric region of the X Chromosome at Xp11 found so far in a limited group of girls with HI.
In Drosophila, sex is determined by the ratio of the X chromosomes to autosomes.
