Hi Patty!
Patti L and I were talking about all the possible genetic mixes Adam and Mercy's kids could be and it brought up a few questions about walkers themselves...
Do walkers always breed true? Or can they have human babies if one of the parents is human? Or can two walker parents have a human child if they have human genes somewhere in their DNA?
If Mercy's parents' genes had mixed differently, was there a chance that she could have been born human, but been able to have walker children?
