Everyone knows that humans have 23 pairs of chromosomes, right? But back in the 1930s, the correct answer would have been 24. So where did that extra pair go?

In this episode from our series exploring 100 ideas in genetics, we explore the discovery of chromosomes – the strands of genetic material within every living cell – take a look at Lyonisation, and solve the case of the missing chromosomes.
