Palearctic water frogs (genus Pelophylax) are an outstanding model in ecology and
evolution, being widespread, speciose, either threatened or threatening to other species …

Haploid cells are a kind of cells with only one set of chromosomes. Compared with
traditional diploid cells, haploid cells have unique advantages in gene screening and drug …

Hybridogenesis is a hemiclonal reproductive strategy in diploid and triploid hybrids. Our
study model is a frog P. esculentus (diploid RL and triploids RLL and RRL), a natural hybrid …

Gametogenesis produces gametes as a piece of genetic information transmitted to the
offspring. While during sexual reproduction, progeny inherits a mix of genetic material from …

Interspecific hybridization may trigger the transition from sexual reproduction to asexuality,
but mechanistic reasons for such a change in a hybrid's reproduction are poorly understood …

Hybrid taxa from the genus Pelophylax can propagate themselves in a modified way of
sexual reproduction called hybridogenesis ensuring the formation of clonal gametes …

Meiosis is a conservative process in all sexual organisms which ensures fertility and is
central for producing genetic diversity by recombination and random segregation of parental …

Interspecific hybridization can disrupt canonical gametogenic pathways, leading to the
emergence of clonal and hemiclonal organisms. Such gametogenic alterations usually …

Background: Hybrid taxa exist in nature, but their fitness can vary greatly. Hybrids are
usually thought to have lower viability and survival rate than parental species due to the …
