Challenging diagnoses of tetraploidy/diploidy and trisomy 12: utility of first-tier prenatal testing methods [PDF]
Frontiers in Genetics, 2023 Introduction: Chromosome mosaicism and low-grade mosaicism present a challenge for diagnosis in the era of SNP array and NGS. Tetraploidy is a rare numerical chromosomal abnormality characterized by the presence of four copies of each chromosome.

Genomic convergence toward diploidy in Saccharomyces cerevisiae. [PDF]
PLoS Genetics, 2006 Genome size, a fundamental aspect of any organism, is subject to a variety of mutational and selection pressures. We investigated genome size evolution in haploid, diploid, and tetraploid initially isogenic lines of the yeast Saccharomyces cerevisiae ...

Ploidy Variation and Spontaneous Haploid-Diploid Switching of Candida glabrata Clinical Isolates
mSphere, 2022 The human fungal pathogen Candida glabrata is phylogenetically closely related to Saccharomyces cerevisiae, a model eukaryotic organism. Unlike S. cerevisiae, which has both haploid and diploid forms and a complete sexual cycle, C. glabrata has long been

When Hymenopteran Males Reinvented Diploidy [PDF]
Current Biology, 2005 In most plants and animals, a consistent relationship exists between the DNA content of a cell and its metabolic activity. The male-haploid sex determination of Hymenoptera and other arthropods may therefore impose a particular selective pressure upon males, which must evolve adaptations to cope with a genomic DNA reduced by half compared with that of ...

Diploidy within a Haploid Genus of Entomopathogenic Fungi [PDF]
Genome Biology and Evolution, 2021 Abstract Fungi in the genus Metarhizium are soil-borne plant–root endophytes and rhizosphere colonizers, but also potent insect pathogens with highly variable host ranges. These ascomycete fungi are predominantly asexually reproducing and ancestrally haploid, but two independent origins of persistent diploidy within the Coleoptera ...
