American scientists succeeded in cloning the black ferret, a species




In the United States, for the first time, one of the endangered animals, the black-footed ferret, has been successfully cloned. The female, nicknamed Elizabeth Ann, was born in December, but she was introduced to the public just now. The ferret was cloned using frozen genetic material from a ferret that died more than 30 years ago.

In December, for the first time, American scientists succeeded in cloning the black ferret, a species that was considered extinct 30 years ago. The unique animal, nicknamed Elizabeth Ann, was the first successful cloning of an endangered species in North America. The individual is now doing well and lives at the NBFCC National Ferret Conservation Center.
Elizabeth Ann is a marvel of cloning and a hope for her kind, according to scientists. The specimen was cloned using frozen cells from a female black-footed ferret that had died over 30 years ago. A female domestic ferret was used as a surrogate mother. In addition to Elizabeth Ann, two ordinary ferrets were born, as well as another black-footed ferret, but he did not survive.
If, as an adult, Elizabeth Ann continues to breed and be able to bear offspring, she will greatly increase the limited genetic diversity of the species and increase its chances of survival. "Without normal genetic diversity, a species often becomes more susceptible to disease and genetic abnormalities, as well as limited adaptability to wildlife and reduced birth rates," NBFCC staff explained.
There are less than 500 black-footed ferrets in the wild. The species was listed as endangered in 1967, and was considered extinct in the wild in 1979. However, in 1981, a Wyoming farmer discovered a small population of these ferrets, which were later used for a breeding program. In the coming months, researchers hope to produce more clones of black-footed ferrets, and are also looking for specimens in the wild.
