Vanellus (Charadriidae; Charadriiformes) comprises around 20 species commonly referred to as lapwings. In this study, by integrating cytogenetic and genomic approaches, we assessed the satellite DNA (satDNA) composition of one typical species, Vanellus chilensis , with a highly conserved karyotype. We…
Simple Summary The evolutionary origins and dynamics of sex chromosomes are among the most challenging topics in the field of Evolutionary Biology. Despite ongoing research, many important aspects of sex chromosome evolution remain unresolved. One intriguing question is why do sex chromosomes tend to…
Scleropages formosus (Osteoglossiformes, Teleostei) represents one of the most valued ornamental fishes, yet it is critically endangered due to overexploitation and habitat destruction. This species encompasses three major color groups that naturally occur in allopatric populations, but the evolutionary…
Simple Summary In animals, several species contain substantial chromosomal and genomic variation among their populations, but as to what could have driven such diversification is still a puzzle for most cases. Here, we used molecular cytogenetic analysis to expose the main genomic elements involved in…
