Then we will agree to disagree on this one.
Since this post died in April 2009, there are no less than 9 pages of results when you type "homozygous spider" into the search bar. Granted, not every single one of those posts are on this exact topic, but more than a handful of them are. Most recently, there is a 13 page thread on the topic that has its last contributing post dated August 1, 2013 (and it's first on September 17, 2012). Shouldn't you be able to find the relevant conversation you're seeking regarding this topic there instead of pulling for a 3.5 year old three page thread to be revisited?
Just sayin'...
