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.

European Journal of Pediatric Surgery, 2008 BACKGROUND: Surgery is the first line treatment for low-grade neuroblastomas. In stage I tumors, the presence of MYCN amplification is rarely detected and the Shimada histology is not always taken into consideration when deciding on the treatment.

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 ...

Sex and diploidy in Armillaria mellea
Experimental Mycology, 1978The life cycle and sexuality of Armillaria mellea are poorly understood. The mating behavior is atypical, and laboratory fruiting is rare. Genetic studies reported herein are based upon monosporous progeny from 27 distinct fruiting bodies and reveal A. mellea as a bifactorial heterothallic fungus.

Evidence for diploidy and mating in trypanosomes
Nature, 1980The question of whether any sexual process takes place at some stage of the life cycle of the trypanosome has often been raised and crosses between different drug-resistant strains have provided no convincing answer. Multinucleate forms of trypanosomes have been observed by electron microscopy but their significance and origin remain obscure.

The coexistence of haploidy and diploidy in yeasts
Experientia, 1959In einigen Hefearten kommen haploide und diploide Zellen zusammen vor. Es wird angenommen, dass diese Koexistenz besondere Vorteile fur die Anpassung der Hefe an Milieux mit schnell wechselnden Bedingungen bietet. Die Vorteile der Haploidie und Diploidie erganzen sich, ohne dass sich die Nachteile der einen oder andern Form auswirken.
