M-FISH pseudocolor image of a normal oocyte metaphase (23,X) with (a) inverted DAPI stained chromosomes inset and (b) corresponding karyotype. (c and d), Hyperploid oocyte 24,X+18 showing nondisjunction, with the additional chromosome 18 indicated by an arrow. Pseudocolor image of (e) sperm prematurely condensed chromosomes in an injected oocyte (f) karyotyped as 23,X. All chromosomes are shown in M-FISH option to demonstrate probe specificity (flat color).
