The specialized trade of chicken sexing has a particular importance in the poultry industry.
The sex of mammals can often be determined using sexually dimorphic characteristics.
[2] Assisted physical sexing is relevant in vertebrates with cloacae (e.g. birds, reptiles or amphibians) when there is no external sexual dimorphism.
In veterinary practice, fibroscopy is used under general anaesthesia in birds such as parrots.
[3] Molecular sexing is a set of techniques that use DNA for determining sex in wild or domestic species[4] (population studies, farming, genetics) or humans (archaeology, forensic medicine[5]).
