Male mice who are heterozygous for distorting and non-distorting alleles at the t-haplotype transmit the driving t-haplotype around 90% of the time - a drastic departure from Mendelian expectations. This selfish act comes at a cost. The mec...
The role of conflict in the formation and maintenance of variant sex chromosome systems in mammals [0.03%]

The XX/XY sex chromosome system is deeply conserved in therian mammals, as is the role of Sry in testis determination, giving the impression of stasis relative to other taxa. However, the long tradition of cytogenetic studies in mammals doc...

Small, fragmented or isolated populations are at risk of population decline due to fitness costs associated with inbreeding and genetic drift. The King Island scrubtit Acanthornis magna greeniana is a critically endangered subspecies of the...
The role of satellite DNAs in the chromosomal rearrangements and the evolution of the rare XY1Y2 sex system in Harttia (Siluriformes: Loricariidae) [0.03%]

We present genome assemblies for 18 snake species representing 18 families (Serpentes: Caenophidia): Acrochordus granulatus, Aparallactus werneri, Boaedon fuliginosus, Calamaria suluensis, Cerberus rynchops, Grayia smithii, Imantodes cencho...
Drift drives the evolution of chromosome number II: The impact of range size on genome evolution in Carnivora [0.03%]
染色体数量进化中的漂变作用 II: 食肉目动物分布范围大小对其基因组进化的影响

Michelle M Jonika et al.
Chromosome number is a fundamental genomic trait that is often the first recorded characteristic of a genome. Across large clades, a common pattern emerges: many or even most lineages exhibit relative stasis, while a handful of lineages or ...

The first record of captive-bred red foxes (Vulpes vulpes) dates to 1896 when a breeding enterprise emerged in the provinces of Atlantic Canada. Because its domestication happened during recent history, the red fox offers a unique opportuni...
