Mystery Lesser Clutch? Help ID?

[dr del]

Hi,

Platty x lesser gives platties, BEL's, lessers, and "het platties." The normal would have been the only one with the hidden mutation. The hidden mutation would cause a lesser to display the platty phenotype.

Wouldn't it also give normals which would make any "het platties" impossible to identify so you would have to call all non-visuals 50% poss het platties?

platty x lesser would technically also produce BELs that carry the daddy trait, right?

[dr del]

Hi,

I don't think so.

If the platty daddy gene is in the same location as the lesser gene then a BEL can't be carrying it.

Platty x anything will not produce any normals. All snakes will carry either the Lesser gene or the Daddy gene.

And as to the Platty - Lesser breeding.

At least after this thread i know more about the Platty!
Amazing clych - good for you

Absolutely awesome! Congrats!

[hgrub]

just curious, is there any "platty" combo out there? If so, do they looks much different than "lesser" combo...apart from the price tag?

So has anyone every held back all the "normal" offspring from a few clutches of lesser X normal and bred back the lesser to the normals to see if by chance it would produce a Platty? If Plattys act as a co-dom/homozygous animal and you bred it to a normal you would get 1/2 lessers and 1/2 normals 100% "Het" Platty. If you bred a Platty to a Normal 100% "Het" Platty you would get Platty, Lessers and Normals poss. "het" Platty. Why wouldn't the normals be 66% if the Platty acts as the homozygous form and the normal acts as the 100% het. Also could we assume that every lesser is 100% het. for Platty? If you breed any Lesser to a Platty or to a Normal 100% "Het" Platty you get Plattys right.... ? Still a little confused

No, when you put it into a square, one of the wild-type alleles from the lesser pairs up with the lesser allele from the platty, while the other wild-type allele from the lesser pairs up with the hidden allele from the platty.

The reason you have 50% possible het platties in the clutch from this thread is because there are wild-type alleles from both parents. Your odds are theoretically 1:4 platinum, 1:4 lesser, 1:4 "het platinum", and 1:4 normal - thus 50% poss het platties.

Lots of people tried that when lessers were first sold, there were a lot of normal girls held back from lesser x normal clutches and bred back to lessers, no platinums were produced.

If Plattys act as a co-dom/homozygous animal and you bred it to a normal you would get 1/2 lessers and 1/2 normals 100% "Het" Platty. If you bred a Platty to a Normal 100% "Het" Platty you would get Platty, Lessers and Normals poss. "het" Platty. Why wouldn't the normals be 66% if the Platty acts as the homozygous form and the normal acts as the 100% het.

Platinum x hidden gene carrier will produce platinums, lessers, and normal looking animals that carry the hidden gene. The platinum passes either the lesser gene or the hidden gene to it's offspring, regardless of what the other parent is.

Also could we assume that every lesser is 100% het. for Platty? If you breed any Lesser to a Platty or to a Normal 100% "Het" Platty you get Plattys right.... ? Still a little confused

I guess you could say the lesser is het for platinum in the same way it is het for leucistic, if that makes it easier for you to wrap your head around it. You still need a platinum or normal looking hidden gene carrier to produce a platinum though.
