If you're referring to the shark in the news article, her offspring are not genetic clones.
"In sharks, asexual reproduction can occur when a female’s egg is fertilised by an adjacent cell known as a polar body, Dudgeon says. This also contains the female’s genetic material, leading to “extreme inbreeding”, she says."
Which is odd because genetic clones would be far healthier than the inbred offspring from above.
