Question

Define totipotency

Answer 1

Totipotency is the ability of a living cell to express all of its genes to regenerate a whole new individual. Totipotent cells from plants have been used in tissue-culture techniques to produce improved plant materials that are pathogen-free and disease-resistant. Totipotent cells from animals are now being used to clone mammals, although ethical questions remain over whether cloning a human should be done.
