Photic Sneeze Reflex

I have always noticed that I sneeze when outside in bright light. Erin also seems to exhibit this response on occasion and when we took Ryan outside this week he did too. A quick google search lead me to some interesting information about this phenomena. It appears to be an autosomal dominant condition, so it isn't a surprise that the kids have it too (Jay, btw, does not have this reflex). I found this article on the Scientific American website about it:http://www.scientificamerican.com/article.cfm?id=looking-at-the-sun-can-trigger-a-sneeze

Genetics is such an interesting subject to me (nerdy science teacher talking here!). From time to time, I really enjoy looking at the kids and making note of the traits that they obviously got from me or from Jay.
