Monica Mares (36) could see up to 18 months in prison if found guilty of incest with her son Caleb Peterson (19) by New Mexico courts.

The sentence is highly likely since the two have decided to go public and raise awareness about Genetic Sexual Attraction "GSA" relationships.

Monica was 16 when she gave birth to Caleb and gave him up for adoption. It wasn't until last year that the two reconnected through Facebook.
