The present invention is generally directed to Matrimony (Mtrm) nucleotide sequences, polypeptides expressed from the nucleotide sequences and methods employing the Mtrm nucleotide and polypeptide sequences. The Mtrm nucleotide sequences of the invention express a dosage dependent polypeptide that mediates achiasmate chromosome disjunction. In particular, reduction in the amount of the Mtrm polypeptide will cause nondisjunction in the achiasmate chromosomes.
