Just a couple things. Firstly, that picture in the above post isn't a Roswell boa! Beautiful, but not a Roswell so to the OP don't get confused there. I thought that they were thinking Roswells were recessive though I'm not certain either. Dominant traits are traits where the mutant gene is dominant over wild type and visually appear the same whether homozygous or heterozygous. With codominant traits the mutant gene is dominant over wild-type as well, but there is a visual difference between the homozygous and heterozygous forms. Heterozygous and codominant are not synonyms though they are misused as such quite often.
