Article Synopsis
- Host species that are closely related have similar microbial communities, but the roles of genetic admixture and environment on these communities are not well understood.
- The study examined the effects of host genetic differences and environmental factors on the gut microbiomes (including bacteria, fungi, and parasites) of two subspecies of house mice and their hybrids, both in the wild and in laboratory settings.
- Results showed that environmental factors predominantly shaped microbiome composition, while genetic differences had a significant impact, especially on fungi, indicating that host genetics and environmental influences are crucial for understanding host-microbiome interactions.
Article Synopsis
- The study examines the introgression of Y chromosomes from eastern house mice into western house mice in Central Europe, focusing on the mechanisms and traits involved.
- Researchers created two special mouse strains to investigate how the Y chromosomes from different subspecies affect various male fitness traits, noting negative impacts when the domesticus Y was present in musculus mice.
- Results indicate that while the domesticus Y chromosome is detrimental to musculus males, the musculus Y can provide some advantages to domesticus males, supporting the idea of a one-way introgression pattern from musculus to domesticus.
Genetic diversity in animal immune systems is usually beneficial. In hybrid recombinants, this is less clear, as the immune system could also be impacted by genetic conflicts. In the European house mouse hybrid zone, the long-standing impression that hybrid mice are more highly parasitized and less fit than parentals persists despite the findings of recent studies.

Consistent with Haldane's rule, the Y chromosome has been considered counterselected and hence not to introgress across the European house mouse hybrid zone. However, recent studies detected massive invasion of Y chromosomes into territory.

Although hybrid sterility occurs almost universally among animal and plant species, most of our current knowledge comes from the classical genetic studies on Drosophila interspecific crosses or introgressions. With the house mouse subspecies Mus m.
