Alternative forms of Aneuploidy in a 2N = 8 organism

Aneuploidy occurs when the number of chromosomes of a particular pair is unbalanced. Given a diploid karyotype with four chromosome pairs, variants include nullisomics missing both members of a pair, monosomics missing one member of a pair, and trisomics with one extra chromosome for a pair.
