For anyone who has read Far from the Tree by Andrew Solomon, you know that his premise is that diversity is what unites us all. He explains that individuals from different families who have the same type of trait or condition are often more like each other than the families they come from, hence the title of the book. He writes, among other things,...

Another common myth is that there is a really high risk for birth defects when people who are related to each other have children together. In actuality, the risk is increased, but n...

Genetic Mythbusters - Part I

In this post I thought I would start talking about some general genetics myths that I find many people share. First, the idea of diseases or disorders skipping a generation. From a genetic standpoint, there really is no such thing as skipping a generation. This is because you cannot pass on what you don't have. So if your father has, for example, a...
