Insects display extraordinary diversity in sperm form and reproductive anatomy, reflecting a complex interplay of evolutionary pressures from mating systems, sperm competition and cryptic female ...

Social insects exhibit a remarkable array of genetic systems that underpin their complex reproductive ecologies and eusocial organisation. Among these, haplodiploidy and paternal genome elimination ...

While most animals reproduce sexually, some species rely solely on females for parthenogenetic reproduction. Even in these species, rare males occasionally appear. Whether these males retain ...

SMBE Journals (Molecular Biology and Evolution and Genome Biology and Evolution) Further analysis of PifA and PifB revealed that they exhibit many of the characteristics of eukaryotic host-associated ...

A collaborative study from the University of Kyoto in Japan, and the Institute of Evolutionary Biology in Barcelona, Spain, reported a new method for editing genes in cockroaches and a variety of ...

Insects that spread disease and damage crops could be controlled by inserting poisons from spider and sea anemone venom into males’ reproductive systems, killing females they mate with. Samuel Beach ...
