Journal of Pharmacy and Bioallied Sciences, 2020 Background: Methods to analyze progression of carcinogenesis and stage of cancer are vital nowadays due to the high prevalence of these lesions. DNA ploidy analysis is one such important method in early diagnosis and improving prognosis.

Recombination and the evolution of diploidy. [PDF]
Genetics, 1992 Abstract With two copies of every gene, a diploid organism is able to mask recessive deleterious mutations. In this paper we present the analysis of a two-locus model designed to determine when the masking of deleterious alleles favors the evolution of a dominant diploid phase in organisms that alternate between haploid and diploid ...

Effects of ploidy and recombination on evolution of robustness in a model of the segment polarity network. [PDF]
PLoS Computational Biology, 2009 Many genetic networks are astonishingly robust to quantitative variation, allowing these networks to continue functioning in the face of mutation and environmental perturbation. However, the evolution of such robustness remains poorly understood for real

Ancient evolutionary trade-offs between yeast ploidy states. [PDF]
PLoS Genetics, 2013 The number of chromosome sets contained within the nucleus of eukaryotic organisms is a fundamental yet evolutionarily poorly characterized genetic variable of life.

Dominance learning in diploid genetic algorithms for dynamic optimization problems [PDF]
, 2006 This paper proposes an adaptive dominance mechanism for diploidy genetic algorithms in dynamic environments. In this scheme, the genotype to phenotype mapping in each gene locus is controlled by a dominance probability, which is learned adaptively during

The Evolution of haplo-diploidy and its consequences for the Red Queen Hypothesis (RQH) [PDF]
, 2016 Haplodiploidie tritt bei Insekten, Spinnentieren und Rädertierchen auf. Sie hat sich innerhalb dieser Gruppen mindestens 20 mal unabhängig voneinander und durch unterschiedlichste Mechanismen entwickelt (Normark 2003). Die vorliegende Arbeit beschäftigt

Cryptic fitness advantage: diploids invade haploid populations despite lacking any apparent advantage as measured by standard fitness assays. [PDF]
PLoS ONE, 2011 Ploidy varies tremendously within and between species, yet the factors that influence when or why ploidy variants are adaptive remains poorly understood.
