A crossbreed is an organism with purebred parents of two different breeds, varieties, or populations. Crossbreeding, sometimes called "designer crossbreeding", is the process of breeding such an organism, often with the intention to create offspring that share the traits of both parent lineages, or producing an organism with hybrid vigor. While crossbreeding is used to maintain health and viability of organisms, irresponsible crossbreeding can also produce organisms of inferior quality or dilute a purebred gene pool to the point of extinction of a given breed of organism.
Limited mutton sheep hybridization breeding pen
The utility model discloses a limit type mutton sheep hybridization breeding pen, and particularly relates to the technical field of mutton sheep breeding, the limit type mutton sheep hybridization breeding pen comprises breeding pen bottom frames, two fixing side frames and a supporting frame, the two fixing side frames are both fixed on the upper surface of the breeding pen bottom frames, the supporting frame is fixed on one side of one breeding pen bottom frame, and the supporting frame is fixed on the other side of the breeding pen bottom frame. A limiting pushing assembly is arranged in the supporting frame. The limiting and pushing assembly comprises a linkage screw rod, a transmission motor, a sliding sleeve block, a linkage strip and a linkage block. The limiting and pushing assembly is adopted, a piece of hybridized mutton sheep is placed between the fixing side frames, the piece of hybridized mutton sheep can thoroughly enter the position between the two fixing side frames, a second piece of hybridized mutton sheep is placed between the two fixing side frames, and the second piece of hybridized mutton sheep is rapidly limited to enter the position between the two fixing side frames. Mutton sheep with two ends hybridized can be rapidly limited for hybridization breeding and can be rapidly driven to a designated position, and the hybridization breeding speed is higher.

Molecular markers and specific primers and identification method for identifying t. obscurus, t. jordani and hybrid t. obscurus x t. jordani
ActiveCN119776544BClimate change adaptationMicrobiological testing/measurementBiotechnologyMorphological trait
The application discloses a molecular marker and specific primers and an identification method for identifying Takifugu obscurus, Takifugu poecilonotus and hybrid Arlea japonica. The application can realize multiple test results through one-time PCR, and simultaneously complete the rapid identification of the three species of Takifugu obscurus, Takifugu poecilonotus and hybrid Arlea japonica. The application provides a fast and accurate identification method for Arlea japonica variety identification, solves the problems of difficult naked-eye differentiation and low operation accuracy of morphological feature differentiation, and realizes the characteristics of easy result judgment, high conservation, high accuracy and the like. The application provides technical support for variety identification and parent selection of the special economic fish, provides a train of thought for further carrying out genetic scientific research of hybrid Arlea japonica, and is favorable for promoting the vigorous development of the hybrid Arlea japonica breeding industry.
