Because haploids are much less fit than heterozygous diploids, our working hypothesis is that changes in ploidy, including whole genome ploidy and aneuploidy, occur frequently under drug stress and that they make major contributions to the rapid appearance of genotypic and phenotypic diversity, in part by promoting persistence.
Haploids are interesting for fundamental research, but their main utility is to produce DH lines, which are extremely useful tools for basic and applied research, including breeding programs (Chupeau et al.

For example, diploids carry twice as much DNA as haploids and may be expected to accumulate new beneficial mutations at a higher rate (Paquin and Adams, 1983).
Bacteria, many fungi, and certain stages of plants survive well as haploids.
