Hybridization refers to the process of mating between individuals of two different natural populations, that is, the process of sexual mating between genetically different groups or between individuals with different genotypes. Hybridization of turtles occurs in both natural and domesticated conditions, and at the beginning, hybrid turtles were not deliberately bred by people, but due to various reasons, two or more kinds of turtles were mixed, so that these turtles were mated in the natural environment to obtain hybrid varieties.
At present, hybrid turtles come in a variety of forms, and hybrid varieties emerge in an endless stream, including varieties of inbreedings and hybrids of distant relatives. Black-necked turtles of different genera are hybridized with Anhui big-headed grass turtles; money turtles of different genera and stone turtles of different genera are hybridized; Chinese flower turtles of different families are hybridized with Brazilian turtles. However, turtles with large ecological types cannot be hybridized, such as tortoises and water turtles. In general, there is more hybridization between turtles of the same ecological type or mating and breeding environment. Some aquatic turtles can also mate with semi-aquatic turtles, such as the money turtle and the sawtooth turtle.
Hybrid turtles can be divided into purebred two-parent hybrid type, hybrid and purebred parent hybrid type, and non-purebred parent hybrid type according to the type of parent. Purebred biparagus refers to the offspring produced by hybridization between different species of turtles, which are often heterozygotes of a single phenotype, with two alleles, one dominant and one recessive. The resulting individuals are often intermediates similar to parents or individuals who combine the characteristics of both parents, but exceptions will arise. Hybrid and purebred parent hybridization refers to the offspring of one parent being a hybrid turtle and the other being a purebred parent. Non-purebred twin hybrids are the offspring of both parents who are hybrid turtles.
With the advancement of science and technology and the development of the economy, hybrid turtles have slowly gained the recognition of farmers, and try to artificially breed new hybrid turtle species to obtain greater economic benefits. For example, the Ai's turtle trotted by the trottering of the money turtle and the stone money turtle, the hybrid black obtained by the mating of the black-necked turtle and the Anhui big-headed grass turtle, the black gold obtained by the hybridization of the black-necked turtle and the gold turtle, the hybrid turtle such as the Ou's closed-shell turtle trotted by the tropic turtle and the Pan's closed-shell turtle, the appearance and value of these hybrid turtles have been praised by the industry, and they have continuously cultivated better offspring and sub-generations from research. At present, there are more than 100 kinds of artificially bred hybrid turtle species, among which the breeding technology of the two varieties of hybrid turtles, Ai's turtle and hybrid black, has been relatively mature and can be cultivated in batches.
In recent years, in order to obtain greater benefits, some merchants in the turtle market have mixed hybrid turtles into pure-bred turtles for trading, such as using hybrid black as a purebred black-necked turtle and hybrid south stone as a purebred south stone, disrupting the market order, harming the interests of farmers, and making some new farmers lose confidence in the turtle market. Therefore, honest trading is particularly important. New farmers should learn more to identify the species and appearance of turtles, which also plays an important role in improving their own breeding experience.
