Orange Milkbacks?

[Fingerlakefeeders]

Noticed a few of these in a mixed culture of Porcellio laevis Milkback x Orange. Other than the fact nobody else has been able to do the cross, I do not believe these are a cross due to the expression of melanin in the cuticle. I found 11 individuals in a culture of several hundred. Most of the others were normal Milkbacks. I purposefully did not feed any food with significant carotenoids to avoid any false positives. Not sure if it will take, but I have isolated them.

Did the seller say about that the seller have both of those isopods (Porcellio laevis Milkback and Orange)?

Update - there are some orange F2s. Evidence suggests either there was a cross, however unlikely, or it is a spontaneous mutation. Once again, I am flummoxed by the genetics.

I notice the milkbacks revert to dairy cow sometimes, curious if some of these will revert to orange dairy cow, good luck

Thank you, Sir! I appreciate the feedback.

As evidenced by the pic, some of the original stock isolated became very ordinary looking. Not all, though. I took another look last night and the F2s are quite variable. There are regular milkbacks, pale yellow milkbacks, whites, yellows, oranges, and pieds. Like I stated earlier, I have no idea what is going on. Fingers crossed.
