Species Transgenic Animals Examples

Other animals include pig goat cow sheep fish etc.

Species transgenic animals examples. This paper examines questions of where ethical issues about transgenic animals stem from how we make ethical decisions and whether ethical issues concerning transgenic animal production are different from those in the production of n on-transgenic animals. To date transgenic research has shown that it is unlikely that the insertion of a single gene from one species into an animal of another species would change the animals phenotype. It has been observed that transgenic pigs having enhanced growth rate and efficient feed conversion exhibit reduced reproductive performance and may suffer from arthritis and dermatitis etc.

Transgenic animals whose genome has been altered to produce pharmaceuticals offer some advantages over traditional methods of drug production. C There may be high mortality rate and other deleterious effects on animals used by researchers to create transgenic breeds. A transgenic animal is one that carries a foreign gene that has been deliberately inserted into its genome.

The foreign gene is constructed using recombinant DNA methodology. In the interest of educating the public about transgenic animals and determining their effect on society the methods of creating transgenic animals is discussed. Sheep goats pigs cows rabbits rats mice fish insects parasites and even humans have previously been used in this modification process.

For example the insertion of a single human gene into a mouse would not be expected to produce an observable human characteristic. Similarly transgenic sheep expressing growth horm6ne may show diabetic like. The offspring was much larger than the parents.

Transgenic animals are those that have been genetically modified. Transgenic animals that carry genetically engineered genes from other species have great potential to improve human welfare. Transgenic animals can be specifically designed to allow the study of how genes are regulated and how they affect the normal functioning of the body and its development.

It examines one example of an application of a utilitarian approach. Dolly the sheep was the first mammal to be cloned from an adult cell. Theoretically all living beings can be genetically manipulated.
