Reptiles epitomize the variability of reproductive and sex determining modes and
mechanisms among amniotes. These modes include gonochorism (separate sexes) and …

With more than 70,000 living species, vertebrates have a huge impact on the field of biology
and research, including karyotype evolution. One prominent aspect of many vertebrate …

Hybrid sterility, a hallmark of postzygotic isolation, arises from parental genome divergence
disrupting meiosis. While chromosomal incompatibility is often implicated, the underlying …

Several recent studies have produced comparative maps of genes on amniote sex
chromosomes, revealing homology of gene content and arrangement across lineages as …

Telomeres are nucleoprotein complexes protecting the physical ends of linear eukaryotic
chromosomes and therefore hel** to ensure their stability and integrity. Additionally …

Bighead catfish (Clarias macrocephalus, Günther, 1864) is an important aquacultural
species that plays a crucial role in the economy of Southeast Asia. Crossbreeding between …

Reptiles are notable for the extensive genomic diversity and species richness among
amniote classes, but there is nevertheless a need for detailed genome-scale studies …

The Hokou gecko (Gekko hokouensis: Gekkonidae, Gekkota, Squamata) has the

Background Unlike the chromosome constitution of most snakes (2n= 36), the cobra
karyotype shows a diploid chromosome number of 38 with a highly heterochromatic W …

Amniotes possess variability in sex determining mechanisms, however, this diversity is still
only partially known throughout the clade and sex determining systems still remain unknown …
