Your explainations are a little more descriptive than mine.

View number 2 on the chart, Salmon X Salmon (or Hypo X Hypo).

It is hard to disagree with salmonboa but that is not my understanding and since I have never bred hypo to hypo my understanding is limited.(very)

Read hypo to hypo on this chart.

some additional information is incorrect.

It labels Supers as being synoymous with dominant.

A animal isn't dominant or co-dominant, the mutation is. Hypomelanism in boas is dominant. Meaning that the heterozygous and homozygous forms have the same phenotype. If the heterozygous and homozygous forms had difference phenotypes it would be co-dominant.

In recessive mutations the heterozygous animals have the same phenotype of wild type animals, because wild type is dominant over the mutation. Make sense?

Not your fault, it is the incorrect information circulating the web. The internet is a great place for information, sadly no one is here to check it.

does not make it correct!!

Hypo is a single gene pair mutation wher the mutant gene is dominant over the normal gene. Further more, it is typically classified as a dominant mutation. Not a co-dominant mutation as many like to say. A dominant mutation will have two distinct Phenotypes or visualy different appearances. So, when identifying outcomes, there are three possible outcomes depending on the genetics of the parents:

Het hypo X het hypo =
25% homozygous hypo
50% heterozygous hypo
25% homozygous normal
or
75% hypo (33% homozygous)
25% normal
since the het and homozygous would have the same phenotype

Het hypo X Homozygous hypo =
50% het hypo
50% homozygous hypo
or
100% hypo (50% homozygous)

Homozygous hypo X homozygous hypo
100% homozygous hypo

It's easy to understand if you consider Normal as a recessive trait from Hypo. The punnet square applies to a dominant trait like hypo just like the recessive traits like Albino.

Remember, when creating a punnet square, the dominant gene is capitilized while the recessive gene is lower case.

_____X____x
X___XX___Xx
x____Xx___xx

So for Albino (a recessive trait), xx would be Homozygous for albino and would express the trait.

And for Hypo (a dominant trait) Xx would be het for Hypo and would express the trait and XX would be homozygous for hypo and would also express the trait!

Good luck Vinnie

Working on educating and correcting the misconceptions of hypo genetics one post at a time. Glad you came over to the right side.
