The Alzheimer's Gene20200409Alzheimer's is a devastating disease - so would you want to know whether it lies in your future? Some online tests say they can tell you how likely you are to develop it, based on which version you have of a single gene. But can we really believe the stats? Would you want to know your own risk level? And what good, bad - and just plain weird - responses do people have to finding out?

Dr Kat Arney makes up her mind about whether to take the test, with the help of social scientist Dr Richard Milne and genetic counsellor Professor Anna Middleton.

The Breast Cancer Gene20200407For centuries doctors have noticed that some types of cancer seem to run in families, but it was only recently that we've started to pin down the genetic culprits. One of these hit the headlines in 2013 when actress Angelina Jolie announced she had a defect in the BRCA1 gene, which can significantly increase the chances of developing breast, ovarian or prostate cancer. Jolie had breast removal surgery in order to reduce her risk of getting ill.

So how does it feel to find out you carry a faulty BRCA gene? What can you do about it? And could new research into these genes help lead to revolutionary new cancer treatments?

Dr Kat Arney speaks to Caitlin Brodnick, author of "Dangerous Boobies: Breaking Up with My Time-Bomb Breasts", and cancer researcher Dr Serena Nik-Zainal of Cambridge University.

The Cyclops Gene20200410What links cyclops lambs, poisonous flowers, and six-toed cats? They're all involved in the story of a gene called Sonic Hedgehog - yes, that is its real name – which has its genetic fingers in all kinds of developmental processes. Sonic Hedgehog helps to decide how many bits you have, where they go, and whether you’re symmetrical, so it’s not surprising that when Sonic makes mistakes there can be serious consequences. We take a look at the mind-bogglingly intricate process of creating a body, and the key role our favourite blue hero plays in making sure everything goes to plan.

Dr Kat Arney is joined by hedgehog experts Dr Bob Riddle of the US National Institute of Neurological Disorders and Stroke, Professor Robert Hill of Edinburgh University, and Dr Natalia Riobo-Del Galdo of Leeds University.

The Ginger Gene20200406Redheads - famed and feared throughout history. From strawberry blonde to sultry auburn, red hair always stands out in a crowd. But where does the redhead gene come from? Does it really affect the way we feel pain? And are redheads really endangered?

Dr Kat Arney finds out with the help of Jacky Colliss Harvey, author of "Red: A History of the Redhead", ginger gene expert Professor Ian Jackson from the University of Edinburgh, and some spicy mice.

The Milkshake Gene20200408Are you dairy intolerant? If so, you’re not alone – more than two-thirds of adults in the world are unable to digest delicious milkshakes and other dairy products properly. 10,000 years ago all humans were like that. So why on earth did some of us evolve the ability to tuck into cheese, butter and cream with a vengeance? And why are farming - and farting - vital parts of the story?

Dr Kat Arney finds out, with the help of evolution expert Professor Mark Thomas of UCL.

The Omnibus Edition20200410Take a deep dive into what you’re made of, as Dr Kat Arney tells the unexpected story of four pieces of human DNA: the ginger gene, the breast cancer gene, the milkshake gene, and the cyclops gene.

People have never been so well informed about their DNA, with tens of millions of home genetic testing kits sold. But behind each of your 20,000 genes is a fascinating story - one that’s being added to every day, as genetics remains on the cutting edge of innovation.

Combining history, archive, anthropology, comedy - and of course, lots of lovely science - we finally give these crucial substances the attention they deserve.
