Nucleolar Dominance in a Tetraploidy Hybrid Lineage Derived From Carassius auratus red var. () × Megalobrama amblycephala () [PDF]
Frontiers in Genetics, 2018 Nucleolar dominance is related to the expression of 45S rRNA genes inherited from one progenitor due to the silencing of the other progenitor’s rRNA genes.

Molecular Phylogenetics of Seven Cyprinidae Distant Hybrid Lineages: Genetic Variation, 2nNCRC Convergent Evolution, and Germplasm Implications [PDF]
BiologyDistant hybridization is key to trait innovation and speciation, with Cyprinidae hybrid phylogeny helping to clarify diversification mechanisms. Yet, a major gap persists in Cyprinidae studies: the stabilization mechanisms of interspecific distant hybrid

Divergent aging of nulliparous and parous mammary glands reveals IL33+ hybrid epithelial cells [PDF]
Nature CommunicationsAging increases breast cancer risk while an early first pregnancy reduces a woman’s life-long risk. Several studies have explored the effect of either aging or pregnancy on mammary stem/progenitor cells, however, the combined effect of both remains ...

Reproductive barriers confirm absence of hybrid speciation and introgression in the Rhodnius pictipes and R. pallescens groups (Hemiptera, Triatominae) [PDF]
Scientific ReportsThe diversification of Rhodnius species has been primarily attributed to vicariance events. Phylogenomic studies have proposed various evolutionary hypotheses – such as incomplete lineage sorting, hybrid speciation, and introgression – to explain the ...

An HMM-based Comparative Genomic Framework for Detecting Introgression in Eukaryotes [PDF]
, 2013 One outcome of interspecific hybridization and subsequent effects of evolutionary forces is introgression, which is the integration of genetic material from one species into the genome of an individual in another species.

Origin and genetic diversity of diploid parthenogenetic Artemia in Eurasia [PDF]
, 2013 There is wide interest in understanding how genetic diversity is generated and maintained in parthenogenetic lineages, as it will help clarify the debate of the evolution and maintenance of sexual reproduction.
