Have I ever eaten a clone? YES
Animal Biotechnology and Genomics Education
What is a clone ?
Cloning, in horticulture and biology, any organism whose genetic information is identical to that of a "mother organism" from which it was created.
Food from clones has been a part of our diet for years. Many common fruits (e.g., pears, apples, oranges and lemons) and several vegetables (e.g., potatoes and truffles) are clones.
Cloning by “natural reproduction” (monozygotic twins)
Animal Biotechnology and Genomics Education
Cloning by embryo splitting – has been done for 20 years

Posted by clerkenwellman “To whom or what is it important that an animal is cloned? The animal? I think not. To the consumer? I can't see how; a pig is a pig for all that.”

“Let consumers decide whether they want to eat cloned/GM foods.”
