Distant hybridization refers to crosses between two different species or higher-ranking taxa that enables interspecific genome transfer and leads to changes in phenotypes and genotypes of the resulting progeny. If progeny derived from distant hybridization are bisexual and fertile, they can form a hybrid lineage through self-mating, with major implications for evolutionary biology, genetics, and breeding. Here, we review and summarize the published literature, and present our results on fish… 
A comparative study of distant hybridization in plants and animals
TLDR
This paper summarizes and compares the similarities and differences in plant and animal distant hybridization, and analyzes and reviews the biological characteristics of their different ploidy progenies and the possible causes of disparity in survival rates.
Establishment and application of distant hybridization technology in fish
TLDR
This study investigated and obtained the main rules regarding inheritance and reproduction related to fish distant hybridization, and established one-step and multistep breeding technologies that were suitable for interspecific hybridization and intraspecific hybridization.
Development and application of biological technologies in fish genetic breeding
TLDR
This review discusses the progress the laboratory has made in the field of chromosomal ploidy breeding of fish, including distant hybridization, gynogenesis, and androgenesis and systematically summarizes the research status and known problems associated with each technology.
Interspecific hybridization of Quasipaa and genetic characteristics of hybrid tadpole
TLDR
Temperature and breeding density significantly affected the growth and development of purebred and crossbred tadpoles and a close genetic relationship was found between the offspring population and the female parent.
Genomic evolution in polyploid vertebrates: Models and progress in research techniques
TLDR
This work reviews the development of theories in WGD studies, summarizes the research models and progress in vertebrates, and discusses the challenges of “omics” research and effective technical strategies to discover feasible means of unravelling the genome evolution of polyploid vertebrates.
A hybrid lineage derived from hybridization of Carassius cuvieri and Carassius auratus red var. and a new type of improved fish obtained by back-crossing
TLDR
The results showed that all the assessed morphological traits were not significantly different between the progenies of the hybrid lineage and their original parents, but the WR-II showed smaller head and higher body compared with its original parents.
A New Type of Allodiploid Hybrids Derived From Female Megalobrama amblycephala × Male Gobiocypris rarus
TLDR
The results show that the hybrids (BR) derived from the inter-subfamily hybridization of female BSB and male RG are an allodiploid fish with 49 chromosomes, and all the measurable traits are significantly different among BR, BSB, and BR.
Production of diploid gynogenetic grass carp and triploid hybrids derived from the distant hybridization of female grass carp and male topmouth culter
TLDR
The results regarding the chromosomal number, DNA content, 5S rDNA and fluorescence in situ hybridization (FISH) showed 2nGGC was derived from gynogenesis with 48 chromosomes and not a hybrid of GC and TC, while 3nGT was a triploid hybrid with 72 chromosomes.
The chimeric genes in the hybrid lineage of Carassius auratus cuvieri (♀)×Carassius auratus red var. (♂)
TLDR
The results provide the new evidence that hybridization can combine the parental genomes, leading to changes in the genotype of the resultant hybrids, and are potentially interesting from the context of both evolution and the genetic breeding of fish.
Rapid genomic DNA variation in newly hybridized carp lineages derived from Cyprinus carpio (♀) × Megalobrama amblycephala (♂)
TLDR
Important evidence is provided that distant hybridization produces rapid genomic DNA changes that may or may not be stably inherited, providing novel insights into the function of hybridization in the establishment of improved lineages used as new fish resources for aquaculture.

Distant hybridization leads to different ploidy fishes
  • Shaojun Liu
  • Biology, Medicine
    Science China Life Sciences
  • 2010
TLDR
It is shown that distant hybridization or the combination of this method with gynogenesis or androgenesis lead to different ploidy fishes with genetic variation, including fertile tetraploid hybrids, sterile triploids hybrids, fertile diploid Hybrid fish, and their derived progenies.
Hybridization and adaptive radiation.
  • O. Seehausen
  • Biology, Medicine
    Trends in ecology & evolution
  • 2004
TLDR
A concept that reconciles views of hybridization and ecological speciation theory is developed and adds a new twist to this debate, which predisposes colonizing populations to rapid adaptive diversification under disruptive or divergent selection.
Hybridization in the Recent Past
TLDR
It is argued that introgressive hybridization may have been a persistent feature of the adaptive radiation through most of its history, facilitating evolutionary diversification and occasionally affecting both the speed and direction of evolution.
Polyploid organisms
TLDR
The formation of fertile polyploids not only promoted the interflow of genetic materials among species and enriched the species diversity, but also laid the foundation for polyploidy breeding.
The formation of diploid and triploid hybrids of female grass carp × male blunt snout bream and their 5S rDNA analysis
TLDR
The obtainment of two new hybrid offspring is the first report of diploid and triploid hybrids being produced by crossing GC and BSB, which have the same chromosome number.
Rapid genome change in synthetic polyploids of Brassica and its implications for polyploid evolution.
TLDR
It is demonstrated that polyploid species can generate extensive genetic diversity in a short period of time and genetic divergence among the derivatives of synthetic polyploids was evident from variation in genome composition and phenotypes.

TLDR
The advantages and challenges of polyploidy, and its evolutionary potential, are considered.
The Formation of the Polyploid Hybrids From Different Subfamily Fish Crossings and Its Evolutionary Significance
TLDR
This study provides genetic evidences at the chromosome, DNA content, DNA fragment and sequence, and morphological levels to support the successful establishment of the polyploid hybrids of red crucian carp × blunt snout bream, the first report on the formation of the triploids, tetraploid, and pentaploids hybrids by crossing parents with a different chromosome number in vertebrates.
Genetic basis and breeding application of clonal diversity and dual reproduction modes in polyploid Carassius auratus gibelio
TLDR
The data suggests that gibel carp are under an evolutionary trajectory of diploidization, and this work highlights future perspectives about the functional divergence of duplicated genes and the sexual origin of vertebrate animals.
ISSR Analysis of Two Species of Scallop(Chlamys farreri,C.nobilis) and Their Intra-And Inter-Species Mating Descendants
TLDR
It was found that the hybrids not only showed higher genetic diversity, but also showed distinct difference from the inbreeding descendants in the genetic relationships with the parents or other descendants.
