Who’s Your Daddy? Low Tech Paternity Testing
I was perusing Dr. Hsien Hsein Lei’s blog and noticed a link to a pretty interesting tool. Dr. Lei describes it as a “low tech paternity test” and it’s a probability calculator that relies on 3 traits: blood type, eye color, and ear lobe type. Yep, it’s sometimes possible to exclude certain father candidates based on these traits.
Apparently attached earlobes (that don’t hang) are a recessive trait, so if a child has unattached earlobes, both parents can’t have attached earlobes. And as far as eye color is concerned, two blue eyed parents can’t have a brown eyed child – so there’s some opportunity for exclusion there (I was interested to see that two dark brown eyed parents can have a blue eyed child, though it’s rather unlikely).
Did you know about the genetics of ear lobes? I learn something new every day.This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.
