This issue we are dealing
with using the Homozygous Beige dominant mutation.
These are the results that can be achieved when breeding a homozygous
beige to other standard and dominant mutation Chinchillas.

Breeding Comments
The homozygous beige is an unusual
mutation to work with. It is usually a pretty pale beige colour over the
whole body with a white tummy.
They are made up the same
as the heterozygous regular beige, except that obviously they are homozygous
for the beige colour, meaning that they have two beige genes. Therefore,
when breeding with this mutation, it always has to pass over one of the beige
genes into the offspring, so not matter what other chinchilla the homozygous
beige is mated to, the offspring will always have beige in them.
Some very pretty coloured chinchillas can be bred using this mutation. The
only problem is, trying to get a good densely furred homozygous beige in
the first place. Beige chinchillas can tend to lack density and be of a softer
fur type than other mutations, so obviously putting double beige genes into
one animal can decrease the density somewhat. So try to work with the best
you can find, as if you are then going to cross this to another mutation,
it will only decrease the fur density further in the offspring produced.
Which if you want to breed the more unusual dominant mutations as those listed
in this guide, you are going to have to mate it to another mutation to achieve
the results you are looking for. So keep an eye out for keeping the strength
in the fur, to avould fluffy, woolly looking chinchillas.
