A woman with two sets of DNA in her body says she could frame her brother by leaving blood he donated to her at a crime scene.Ananya Bashyam, 24, is a 'chimera' as her body is an organism that contains at least two different sets of DNA.She was diagnosed with acute lymphoblastic leukaemia - a type of blood cancer - in October 2021.Her brother, Chaitanya, 21, a college student, saved her life by donating bone marrow in July 2023 – transfusing his new cells into her and replacing hers.This means Ananya now has two sets of DNA – the blood of her brother and the rest of the DNA in her body is hers – also known as a chimera.

00:00 officially a chimera, which is what you call someone with two different sets of DNA within
00:03 their body. So for me, I have my brother's DNA in my blood and my own DNA everywhere else. In about
00:08 three to six months, my blood type will change completely to his. For a little while there,
00:13 I'll actually have two blood types, mine and my brother's. So I got this question a lot about the
00:17 blood transfusions, and so while I have two different blood types, they would have to do
00:22 a type and screen test on me to see which blood type is kind of more dominant, and that's the
00:27 blood they would transfuse me with. But for the rest of my life, if they ever test the DNA in my
00:31 blood, it'll actually be my brother's DNA that shows up, not mine. And so this actually makes
00:35 it really complicated for like crime investigations. Like if I committed a crime and my blood was left
00:42 on the scene and they did a DNA test on it, it would be my brother that would get accused of
00:47 the crime, not me, because it'd be his DNA that showed up. Not saying I want to commit a crime,
00:52 but if I ever did...
