Page 2: Research news on sexing (plants & animals)

Sexing in plants and animals refers to methodological procedures used to determine the phenotypic or genotypic sex of individuals for research, breeding, or management purposes. Approaches range from morphological assessment of sexual dimorphism (e.g., genitalia, secondary sexual characteristics, flower morphology) to cytogenetic and molecular techniques that detect sex chromosomes or sex-linked markers, such as PCR-based assays, karyotyping, or quantitative PCR of sex-specific genes. In early developmental stages or sexually monomorphic species, sexing often relies on invasive or noninvasive sampling (blood, tissue, feathers, leaf tissue) followed by DNA-based tests, which provide high accuracy and are widely used in conservation, livestock production, aquaculture, and plant breeding programs.

Male crickets bulk up, females invest in reproductive organs

A lab study on crickets has revealed sex differences in how the insects direct their nutritional resources to increase chances of generating offspring, finding that females prepare for producing eggs while males prioritize ...

Light-based insect analysis sharpens forensic timelines

Researchers from the Texas A&M College of Agriculture and Life Sciences Department of Entomology and Department of Biochemistry and Biophysics have developed a technique that uses infrared light and machine learning to reveal ...
