Sex chromosomes (SC) evolution is a long-standing question in evolutionary biology. H.J. Muller's century-old theory suggests that SC evolve by fixing a new sex-determining gene (SD) on an ancestral autosome. Over time, sex-specific alleles accumulate, leading to recombination loss and ultimately SC degeneration. While this unidirectional scenario aligns with SC evolution in well-studied …
B chromosomes are enigmatic structural elements in the genome of some organisms. Interestingly, these chromosomes do not recombine with complement A chromosomes and thus followed a different path during evolution, carrying mainly redundant genetic information already present on standard complement chromosomes, in addition to regions of repetitive sequences. In fish populations of the Asty…
During the early stages of prophase I in meiosis, the cells undergo a significant decrease in their transcriptional activity, related to the synaptic states of the homologous chromosomes. This phenomenon is known as Meiotic Silencing of Unsynapsed Chromatin (MSUC), and describes the cascade of chromatin remodeling events, tending to limit gene expression during the onset of meiosis. The e…

Overfishing imposes changes in the life strategy of the populations of organisms, especially in relation to sharks and rays, organisms that make up the group of elasmobranchs. Thus, understanding the structure of populations becomes an important tool for conservation and management of stocks and requires a broad knowledge on genetic, biogeographic, and distribution and occurrence of speci…
In addition to the standard set of chromosomes (A), about 15% of eukaryotes presents supernumerary chromosomes (B). Despite its poor composition in protein-coding genes, the description of transcripts from B chromosomes has changed the view that they are inert structures in the genome. Among fish, in Astyanax genus, the greatest diversity of B chromosomes is found, with the occurrence of …

Very recently the power of next-generation sequencing (NGS) analysis began to be applied to research on supernumerary or B chromosomes of different organisms. However, this technology has not been yet applied to the B chromosomes found in fish species. Results obtained in the Laboratory of Fish Biology and Genetics (IB/UNESP/Botucatu) show that in the population of Astyanax paranae from t…
Supernumerary or B chromosomes are extra genomic structures to standard chromosome complemente and occur in several groups of eukaryotic organisms such as plants, fungi and animals. They may have different origins, including derivation from the autosomal set or sex chromosomes and even as a result of interspecific crosses. The molecular mechanisms that drive the evolution of these segment…
B chromosomes are extra genomic elements to the standard chromosome complement and occur in many organisms. They may have different origins, including derivation of autosomes or sex chromosomes and even as a result of interspecific crosses. The molecular mechanisms that drive the evolution of these segments resemble those of univalent sex chromosomes and may involve gene silencing, hetero…
