Transition from haploidy to diploidy
Nature, 1991As a direct consequence of sex, organisms undergo a haploid and a diploid stage during their life cycle. Although the relative duration of haploid and diploid phases varies greatly among taxa, the diploid phase is more conspicuous in all higher organisms.

Journal of Theoretical Biology, 1979
Abstract A new gene for a new purpose may be created by mutation of a pre-existing gene. But if that original gene is still required for its original purpose, and is to be retained side by side with the new, a spare copy is needed initially as raw material for the innovation. Thus in haploids the original gene must be duplicated before it is modified.

Diploidy for evolving neural networks
Proceedings of the Genetic and Evolutionary Computation Conference Companion, 2018Genetic algorithms and artificial neural networks are two widely-used techniques that can be combined with each other to produce evolved neural networks. Some research has also looked at the use of diploidy in genetic algorithms for possible advantages over the haploid genetic representation usually used, most notably in the form of better adaptation ...
