1. A method of making a viable Issatchenkia orientalis organism that contains N to 2N−1 chromosomes, comprising the steps of:
a) growing parent diploid and/or tetraploid I. orientalis cells in the presence of an agent selected from the group consisting of nocodazole, benomyl, colchicine, para-fluoro-phenylalanine, and combinations thereof; and
b) isolating and identifying at least a portion of the viable daughter cells that contain N to 2N−1 chromosomes, wherein 2N represents the number of chromosomes in wild-type Issatchenkia orientalis.
