TLDR
A recent overview of genomics data, address different approaches applicable to comparative genomics analyses, and illustrate these comparisons to better understand the complex mechanisms under the vertebrate genomes as mentioned in this paper, and summarize the applications in chromosomes research and cytogenomics.Abstract:
The living fishes span a unique and interesting set of animals because of their vast diversity, morphology, ecology, genetics and genomics, and higher importance to biology, economy and culture. During the past decade, the remarkable increase in fish genome sequencing has revolutionized comparative and evolutionary genomics, with the outcome of stimulating insights into vertebrate genome biology. Fish genomics has been transformed rapidly, with the availability of high-quality chromosome level genome assemblies and large collections of sequencing datasets, which are roadmaps for striking discoveries. Landmark achievements are being made; such as the accomplishment of fully assembled lungfish genome which is biggest genome ever sequenced. Here, we highlight current developments in vertebrate’s comparative genomics and discuss how fish genomes could be considered as vital resources for genomic studies. We present a recent overview of genomics data, address different approaches applicable to comparative genomics analyses, and illustrate these comparisons to better understand the complex mechanisms under the vertebrate genomes. We also summarize the applications in chromosomes research and cytogenomics.read more

Fish as Model Systems to Study Epigenetic Drivers in Human Self-Domestication and Neurodevelopmental Cognitive Disorders
TL;DR: It is argued that fish provide model systems to study epigenetic drivers in human self-domestication and will pave the way for future studies using fish as models to investigate epigenetic changes as drivers of human-self domestication and as triggers of cognitive disorders.

TL;DR: Differences in the distribution and abundance of repetitive elements in chromosomes that have undergone remodeling processes during the course of evolution also suggest a possible role for simple repeat sequences in rearranged regions.

Fish as model systems to study epigenetic drivers in human self-domestication and neurodevelopmental cognitive disorders
TL;DR: In this paper , the authors compare genes that carry epigenetic changes in early domesticates of European sea bass with anatomically modern humans and neurodevelopmental cognitive disorders with abnormal self-domestication traits, i.e., schizophrenia, Williams syndrome and autism spectrum disorders.

TL;DR: In this paper , the authors examined the relationship between the genome size, chromosome number and body length across all fishes and found that body length was associated with genome size whereas no relationship was noticed between the GS and the chromosome number.

TL;DR: It is found that genes implicated in cognition show an unexpectedly high rate of duplicate gene retention after the teleost genome duplication event, suggesting a hypothesis for the evolution of the behavioral complexity in fish, which exceeds that found in amphibians and reptiles.
