That would not be really likely if the white coloration is a recessive trait. It would take another chance mutation for some wild colored shrimp to appear. Same applies to red cherry shrimp and reports of sudden "reversions" to wild coloration...this just does not happen (see below). This only applies to intraspecific (i.e. same species, different color morphs) "crosses" though. What's more likely is that you guys have had interspecific (i.e. between two different species) crossbreeding going on at some point in time in your line of shrimp and the results of such crosses rarely, if ever, follow simple mendelian genetics.ToddnBecka wrote:I'd say it's likely that the snowballs are producing some wild-color offspring.
For what it's worth...i've been breeding the snowball shrimp for almost 2 years now and I have never had any brown or red shrimp appear in my tanks. All of my offspring are white. Same applies to my red cherries...all of them are red. Barring any extremely rare and unlikely, chance mutations, if any weird colors appear among your relatively newly purchased offspring (say within a few months), then there must have been crossbreeding going on in your line of shrimp even before you purchased them.
