Verry close .. here is where you went wrong:
>>a non-dominant hypo is "Hh" >>a dominant or Super hypo is "HH" >>a normal (non-hypo) is "hh" >> >>so a non-dominant hypo ("Hh" is het for Super hypo? >> >>and then, >>a jungle is het for Super jungle? >>and motley is het for Super motley?
Dominant only describes the mode of inheritance. It is talking about the genetic mutation itself not that actual animal. Recessive Dominant Co-dominant are the basic ones for boas although there are more.
Recessive means that in order for the physical mutation to occour in the animal it must recieve a mutated gene from each parent. Dominat means that in order for the physical mutation to occour an animal only need to recieve a gene from one of the parents. This would mean the animal is heterozygous. The animal CAN recieve this gene from both parents and visualy you could not tell but genetically it will have a pair of mutated genes or homozygous (or super in boa terms). co-dominant works similar to dominant in the fact that only one mutated gene is required to physically have a difference from a wild type but in this case the presence of two mutated genes forms an alternate physical difference, ie. motley (heterozygous form) and super motley (homozygous form).
Jungle is just het for jungle unless it is stated that it is a super or homozygous jungle, a homozygous (has two jungle genes) is called a super jungle in boa terms. homozygous and super mean the same thing, one is just slang. Same goes for Motley only with motley you can easily visually see the difference between a single mutant motley gene and a pair of mutant genes.
Just remember to think of dominant, recessive, co-dominant etc as describing the condition not the individual animal. As in cancer is a deadly disease, deadly describes the cancer.
homozygous and heterozygous describe the genetics of the individual animal. As in Bob has a bad case of cancer, bad case describes Bobs particular situation with cancer. ----- - Jason F.
