3 results about "Sex selection" patented technology

This invention belongs to the field of plant sex identification technology, and particularly relates to the application of a molecular marker in identifying the sex of *Zephyranthes* plants. The molecular marker is linked to the Y chromosome of *Zephyranthes* plants and comprises a sequence having at least 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99%, or 100% sequence identity with SEQ ID NO:1. The molecular marker provided by this invention can be tightly linked to the Y chromosome of *Zephyranthes* plants, thereby achieving the purpose of early and rapid sex detection. This has significant practical implications for sex selection and proportioning of ornamental garden plants, understanding and protecting endangered *Zephyranthes* germplasm resources, and improving the effectiveness of ex-situ and in-situ conservation management.

Aspects of this invention relate to a novel monoclonal antibody specifically designed to exhibit selective binding affinity towards antigens present predominantly in X chromosome sperm. The antibody is engineered for applications to sex select sperm for cattle breeding purposes.

This invention discloses an intelligent fish fry size, color, and sex selection system based on morphometric feature recognition. The system includes a fry batching module, a diversion and conveying module for processing the fry fed through the batching module, and a fry feature and size discrimination module located above the diversion and conveying module. The fry feature and size discrimination module provides the diversion basis by acquiring fry feature information from fry images. The module includes a shell, a high-definition camera and lighting embedded in the shell facing the diversion slide, and an image processing component installed inside the shell. This invention designs a multi-angle screening system for fry size, body color, and sex, overcoming the three key difficulties in fish fry breeding: size selection, color selection, and sex selection. It effectively solves problems such as cannibalism between larger and smaller fish, selection of ornamental fish, and sex selection at the fry stage, accelerating the artificial breeding process and improving production efficiency.
