A biologist puts her hand in a box with male genetically modified Aedes aegypti mosquitoes at an educational exhibition by British biotechnology company Oxitec in Piracicaba March 5, 2015. Oxitec said its laboratory created the genetically modified male Aedes aegypti mosquitoes, which are set to be released in Sao Paulo in April. A specially-made gene in the male mosquitoes seeks to reduce to number of Aedes aegypti mosquitoes by killing their offspring after mating with wild female mosquitoes. Brazil already has more than 100 000 cases of people with dengue in 2015, according to the City Department of Health. REUTERS/Paulo Whitaker (BRAZIL - Tags: SOCIETY CRIME LAW) 

Austrian Olympic and World show jumping medalist Hugo Simon stands with "E.T. Cryozootech-Stallion", a clone of the gelding show jumping winner E.T. FRH, which is presented at the Top Sire horse show in Bourg-en-Bresse, eastern France February 4, 2007. The stallion, born on June 2, 2006, is a clone resulting from cells taken from the castrated show jumping champion E.T. FRH and is intended for breeders as it carries identical DNA genetic content.

A combination photo shows a cloned fluorescent puppy, a three-month-old beagle, glowing in the dark under ultra-violet light (L) and under daylight (R) at Seoul National University's College of Veterinary Medicine in Seoul May 13, 2009. The puppy is one of "2nd generation Ruppies", offspring of "Ruppy", the world's first transgenic dog which carries fluorescent genes. They took a fluorescent protein, much like that produced by some sea anenomes, and inserted it into the cell of a beagle. The name "Ruppy" is a combination of the words "Ruby" and "Puppy", and the offsprings of such dogs will possess the same fluorescent gene as their mothers.

Snuppy the Afghan Hound, the world's first dog cloned from adult cells by somatic nuclear cell transfer, rests during a photo call at Seoul National University's College of Veterinary Medicine March 12, 2008. A South Korean biotech company is offering dog owners the chance to clone their pet through a service that can cost up to $148,000 for a puppy. RNL Bio, affiliated with the South Korean lab that produced the world's first cloned canine, expects to deliver its first cloned dog in about a year to a U.S. woman in her 50s who saved biological material from her beloved pit bull that recently died.

The world's first cloned camel, Injaz (front), is seen at the Camel Reproduction Centre in Dubai, April 15, 2009. The female camel calf was born on April 8, created from cells harvested from the ovary of an adult she-camel which were grown in culture before being frozen in liquid nitrogen.

Dr Ian Wilmut, leader of the team that created Dolly the sheep - the world's first mammal cloned from an adult cell - faces her as she goes on display at the National Museum of Scotland in Edinburgh, April 9 ,2003. Dolly, who born on July 5 1996 after her creation by the Roslin Institute research centre, died in February 2003 after the decision was taken to "euthanase" her when it was discovered she had a progressive lung disease. She has now been preserved for public display at the Museum.

Genetically engineered angelfish (Pterophyllum) glow in a tank under a blacklight, at a fish farm in Pingtung, southern Taiwan, September 16, 2010. The fish are the world's first fluorescent angelfish which were created by a joint project between Taiwan?s Academia Sinica and Jy Lin, a private biotechnology company. The breed is the largest fluorescent fish in the world which are able to mate and reproduce, said Yu-Ho Lin, Chairman of Jy Lin. The fish are expected to be sold at around $30 after certification.

-PHOTO TAKEN 08FEB05- A Russian scientist Alexander Sotnikov stretches a cloned rabbit for tests at the laboratory outside Moscow, February 8, 2005. Many of those used in the research at the biotechnological centre are clones of genetically-modified rabbits, which have had human genes added to their genomes. Scientists say milk from the resulting rabbits contains protein that helps treat cancer in humans. The centre, just outside Moscow, keeps dozens of these transgenic rabbits for research purposes.

Two featherless chickens peck around in some grass May 22, 2002 at the Hebrew University in Rehovot. Israeli scientists at the Agriculture department of the university have genetically bred bare-skinned chickens as part of a research project to develop succulent, low fat poultry that is environmentally friendly. The naked chicken, as the bird has been dubbed, would also save poultry farmers large amounts of money on ventilation to prevent their chickens from overheating.

UNDATED PHOTOGRAPH - Researchers said on April 26, 1999 that they had genetically engineered goats to produce a human protein used to affect blood clotting -- and then cloned the goats. The team -- at Framingham, Massachusetts -based Genzyme Transgenics Corporation, Tufts University and Louisiana State University -- said their three female goats, shown in this undated photograph, were born last fall.
