Gail, great thread! The way I look at it is nothing is guaranteed in life. Nothing! For instance, I am 5'6" my husband is 6'0 and 2 of my daughters are 5'1 and 5'3. The other one is 5'9. Dont know where the 2 girls got their height from. Another thing is that my great grandmother was an Albino. We have no idea where that came from, deep in our family lines. You can only test for what is in front of you. You never know whats buried deep in any lines.JMO, Great thread and great info...
