TL;DR: A very high rate of sex chromosome turnover in true frogs is shown, which may be driven by rapid mutation-load accumulation due to the low recombination rate in males, suggesting a key role for mutation- load accumulation in non-recombining genomic regions.

TL;DR: In this paper, the authors investigate the evolution of resistance in the aphid Myzus persicae and reveal that the emergence and spread of these mechanisms is influenced by host-plant associations.

TL;DR: The long-term monitoring has showed an increasing birth rate of triploid hybrids in this mixed population of rock lizard species Darevskia, and the frequency of captured males with fully developed reproductive systems and presumably fertile females also increased significantly.

TL;DR: The findings confirm the hybrid nature of D. unisexualis and shed light on heterozygosity and automixis in diploid parthenogenetic forms and suggest a model for diploidal germ cells formation from diploids oocytes without premeiotic duplication of chromosomes in the oogenesis of diPLoid parthensogenetic lizards D.unisexualis.

TL;DR: Comparison of immunocytochemical study of primary spermatocyte nuclei spreads from the leptotene to diplotene stages of meiotic prophase I in two species allows to identify species-specific karyotype features, previously not been detected using conventional mitotic chromosome analysis.
