Transgenic Animals Definition Biology. Relating to an organism whose genome has been altered by the transfer of a gene or genes from another species or breed. A transgenic animal , for instance, would be an animal that underwent genetic engineering.
Sheep, goats, pigs, cows, rabbits, rats, mice, fish, insects, parasites and even humans have previously been used in this modification process. The ability to introduce foreign genes into the germ line and the successful expression of the inserted gene in the organism have allowed the genetic manipulation of animals on an unprecedented scale. Transgenesis is the process by which mixing up of genes takes place.
Transgenic animals are extensively used to study in vivo gene function as well as to model human diseases.
To determine an unknown gene's function; Transgenic animals are those that have been genetically modified. Gmo an organism whose genetic characteristics have been altered by the insertion of a modified gene or a gene from another organism using the. A transgenic organism is one that contains a gene or genes which have been artificially inserted instead of the organism acquiring them through reproduction.
