1 -- Trisomy refers to the presence of a third or extra chromosome instead of the normal pair of a particular chromosome. The most common type of trisomy in infants is trisomy 21 or Down syndrome. Monosomy refers to the presence of only one chromosome instead of the normal pair of chromosomes. Translocations occur when there are breaks in two or more chromosomes with reattachments in new combinations. Structural rearrangements of chromosomes may result from deletions or loss of a chromosome segment or piece.
