Mendelian laws in aquaculture and cuniculture: simple and efficient
Journal Title: Aquaculture, Aquarium, Conservation & Legislation - International Journal of the Bioflux Society - Year 2013, Vol 6, Issue 2
Abstract
Many aquarists, fish or rabbit breeders have at their disposal for reproduction heterogenic populations as a result of segregation, or due to crossbreeding. In many cases, they must buy new brood stock every 2-3 years due to the fact their old brood stock degenerates visible after several generations. The aim of this paper is to underline that there are some low cost and easy to understand principles available with application in animal improvement and production. Color, size and shape are important traits when we describe a product as a phenotypically uniform line, strain or breed, e.g. the albino African catfish, the red eyed swordtail, the Red Blond guppy, the large chinchilla rabbit, the New Zealand white rabbit. A standardized color, shape and size describe better an animal population and thus the said product is promoted better on the market. Two simple examples of applications will be presented in this paper, the case of purification and maintaining of thermo-resistant guppy fish, and the principle of improvement of body size and maintaining the color pattern in Transylvanian Giant rabbit. The key to success is to know what is (are) the recessive gene(s) for every relevant locus.
