After the successful cloning of Dolly the sheep, scientists are hopeful to clone/bring back the mammoth from extinction. Notably well preserved blood in a recent finding of mammoth remains could lead to mammoth stem cells. With these stem cells and the use of elephant eggs to grow an embryo, a baby mammoth could be born. The stem cells could also form gametes, which, if from a female, could lead to both breeding and cloning mammoths. The method of cloning could be fairly similar to the process used to create Dolly the sheep. Although bringing back the mammoth would be beneficial for science, a debate exists arguing the issues. 

A 13 year old Brittany Donovan was born with a fragile X chromosome from her biological father which was a sperm donor. A fragile X chromosome causes slowed learning and can be also classified as retardation. It is said that the child can sue the sperm donor bank that help create her under liability laws.
