First Insight Into Multiple Paternity in the Potato Cyst Nematode <i>Globodera pallida</i> Facing Masculinizing Plant Resistance. [PDF]
This study demonstrated multiple paternity in the potato cyst nematode Globodera pallida: all females were polyandrous. Moreover, the female mating rate with different males appeared to remain stable, i.e., an average of seven fathering males, throughout the adaptation process to a masculinizing potato resistance.

Ploidy Variation and Spontaneous Haploid-Diploid Switching of Candida glabrata Clinical Isolates
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

The evolution of haploidy and diploidy [PDF]
It is remarkable that one of the most fundamental features of an organism — its ploidy level — is so variable among taxa, with life cycles running the entire gamut from complete haploid dominance to complete diploid dominance. Theoretical studies have clarified many important genetic advantages to haploidy (for example, lower mutation load, more rapid ...

Background In gestational trophoblastic disease, the prognosis is related to the genetic constitution. In some cases, taking a biopsy is contraindicated. Methods In a pregnant woman, ultrasound scanning suggested hydatidiform mole.

Evolutionary route to diploidy and sex [PDF]
By using a bit-string model of evolution, we find a successful route to diploidy and sex in simple organisms. Allowing the sexually reproducing diploid individuals to also perform mitosis, as they do in a haploid-diploid cycle, leads to the complete takeover of the population by sexual diploids.

Mutation accumulation may only be a minor force in shaping life-history traits, even when reproduction is sexual. [PDF]
In a previous theoretical study we investigated whether adaptive or non-adaptive processes are more important in the evolution of senescence. We built a model that combined both processes and found that mutation accumulation is important only at those ...
