A poem warning of the dangers of ancestry testing & the consequent risk of ill-founded doubt (with thanks to Sylvia Plath) Daddy give me a break Won't you? Daddy what will it take For you To see That I am a part of you? What do you see when you see me Daddy? Is there any way you can free me Daddy? From you And all that has come from you? I never thought Mummy would stray Daddy The phenotype is a giveaway Daddy Your DNA Was to blame, don't you think? Daddy this gives you a thrill I see Daddy who will you kill? Not she. Is there Someone you think it could be? You told me it’s all a big hoax Daddy That my genes come from the Big Smoke Daddy So what Can be bothering you? Do you want me to be unique Daddy? Does doubt give you all that you seek Daddy? Just know I am perfectly me.
