(a) Electrophoretogram showing the comparison of maternal and fetal peaks after amplification of DNA for the STR marker D21S1414. Triallelic pattern in a fetus with trisomy 21. (b) Monosomy X resulting from paternal nondisjunctionin the IUL there is only one allele (inherited from the mother) for each of the two selected STRs (X22 and HPRT).
