Premeiotic endoreplication is the mechanism of obligate parthenogenesis in rock lizards of the genus Darevskia

This study re-evaluates the fusion hypothesis in Darevskia lizards, revealing premeiotic endoreplication as the mechanism for producing non-reduced eggs in obligate parthenogens.

The fallacy of global comparisons based on per capita measures

The paper shows that per capita measures can misrepresent data for small and large populations and suggests regression-based approaches as a better alternative.

Poorly differentiated XX/XY sex chromosomes are widely shared across skink radiation

The paper identifies shared XX/XY sex chromosomes in skinks and shows their evolutionary stability over 85 million years, challenging the notion that poorly differentiated sex chromosomes are unstable.

Evolution of dosage compensation does not depend on genomic background

The paper shows that dosage compensation mechanisms in reptiles evolved independently despite sharing a common genomic region, indicating genomic background and gene identity, not ancestral content, drive these differences.

Do male and female heterogamety really differ in expression regulation? Lack of global dosage balance in pygopodid geckos

The paper examines gene dosage balance in pygopodid geckos and finds no significant difference in expression regulation between male and female heterogamety.
