Chasing a Ghost Squash

Back in one of my early plant breeding classes, Professor Jim Nienhuis entertained the class with a story about a white butternut squash that he found in his field one day. But the squash, like a ghost, disappeared. Jim and I talked about how he went looking for his elusive, ghostly white squash, applying what he knew about population genetics. You might be scared – unless you understand Hardy-Weinberg Equilibrium!
