"jayf" is correct,the trait we all refer to as "hypo",(regardless of whether it is "salmon",or,"orange-tail",or,a combination of the two.) is a DOMINANT genetic trait...there's no such thing as a "co-dominant" hypo boa!(and,there's nothing "incomplete" about the hereditary transmission of it.)Visual difference between homozygous & heterozygous forms of the trait are not always reliable. The visual appearence of any given gene carrier depends on many different variables. in order to produce a "super hypo" (homozygous) both parents must express the trait,either in het,or,"super" form...calculating the outcome works in a similar way as calculating a recessive gene outcome...het X het= approx. 25% homo/25% non-gene carriers,with the remaining 50% being hets...het X homo= 50% hets/50% homozygous..."super" X "super"= 100% homozygous outcome...if you plug "hypo" into Punnett's square as DOMINANT,the statistical results match what has been proven through breeding...my biggest contention has always been,"what's incomplete about that?"...followed by,"why are we assigning two different genetic labels to ONE genetic trait???" (co-dominant & dominant) if the trait was "Co-dominant" you'd see the leaders in this industry selling 100% supers from het X het breedings,not listing them as "possible supers"! Anyone that tells you "there's no such thing as a heterozygous hypo",clearly needs a class in genetics!(it would probably be "standing room only"too!!! *lol*)
