I'd really appreciate some comments about the colour of two of my E.o.o. yearlings.

The parents are lovely black animals, with white chins and throats, tapering through progressively darker shades of opalescent grey along their bellies towards their black tails. Of the four babies, two are coloured very much like their parents, but the other two have very dark mottled brownish backs, and creamy yellow colouring where the parents have white. Their older sibling (3-yrs-old) is the same colour as the parents.

In the each of the productive clutches laid by these parents, there were at least a couple of albino babies that died in their shells at or very shortly before the hatching date. I have no background information on the parents, but I believe that they may very well be littermates, and that the colour variance is due to shared genetic composition. What I'm wondering is whether or not this yellow (in one case it is becoming fairly bright as the snake matures) indicates that the parents are of intergrade ancestry. I'd also be interested in knowing whether the albino colouration is commonly associated with a lethal factor.
