Single locus complementary sex determination in Hymenoptera: an "unintelligent" design? [PDF]
, 2006 The haplodiploid sex determining mechanism in Hymenoptera (males are haploid, females are diploid) has played an important role in the evolution of this insect order.

Role of HIV RNA structure in recombination and speciation: romping in purine A, keeps HTLV away
, 2013 Extreme enrichment of the human immunodeficiency virus (HIV-1) RNA genome for the purine A parallels the mild purine-loading of the RNAs of most organisms.

Genome Changes After Gene Duplication: Haploidy vs. Diploidy [PDF]
Genetics, 2010 Abstract Since genome size and the number of duplicate genes observed in genomes increase from haploid to diploid organisms, diploidy might provide more evolutionary probabilities through gene duplication. It is still unclear how diploidy promotes genomic evolution in detail.

Ecology and Evolution, Volume 16, Issue 1, January 2026.Genome‐wide data from ddRADseq revealed a latitudinal gradient in genetic diversity in a Taiwanese endemic orchid. This study shows that genomic data not only can help us understand the evolutionary origins of genetic diversity in a species but also uncover its genetic reservoir for future conservation planning.

Comparison of DNA histograms by standard flow cytometry and image cytometry on sections in Barrett's adenocarcinoma [PDF]
, 2012 Background: The purpose of this study was to compare DNA histograms obtained by standard flow cytometry (FC) and high fidelity image cytometry on sections (ICS) in normal gastrointestinal mucosa and Barrett's adenocarcinoma (BAC).

Does diploidy increase the rate of adaptation? [PDF]
Genetics, 1994 Abstract Explanations of the evolution of diploidy have focused on the advantages gained from masking deleterious alleles. Recent theory has shown, however, that masking does not always provide an advantage to diploidy and would never favor diploidy in predominantly asexual organisms.

The Overlooked Threat of Global Warming on Elasmobranch Fertility
Fish and Fisheries, Volume 27, Issue 1, Page 41-55, January 2026.ABSTRACT Climate change is increasingly recognised as a critical threat to global biodiversity, yet its impacts on reproductive processes remain poorly understood in many marine taxa. Elasmobranchs (sharks, skates and rays) represent a particularly vulnerable group due to their peculiar life histories, low fecundity, and diverse reproductive modes.

Triploidy induction in Heterobranchus longifilis (Family: Clariidae) by cold shock [PDF]
, 1999 Triploid was induced in African Catfish (Heterobranchus longifilis) by cold shocking activated eggs at 5 degree C for forty minutes starting 3-4 minutes after fertilization.
