The Black Velvet is indeed a very useful mutation to work
with. Used with other colours, such a Beige, can produce
new mutations. The only obvious point that needs to be
made here is the inclusion of the Fatal combinations
that are shown here, the lethal factor that comes into
play when breeding two Chinchillas together that both
contain Black Velvet. You can still breed together two
Chinchillas that have Black Velvet genes. You will not get
deformed babies, or weak youngsters, or babies dying
in the womb etc.. as some would have you believe. The straight
forward simplicity of the lethal genes is that, to sum
it up, it is impossible to have a homozygous black or double
black gened Chinchilla. So, if the male sperm tries to
fuse with the female egg that also has the genetical make
up of Black Velvet, then they simply do not fuse together,
so a baby is not made. Ofcourse, the male has passed
on plenty of other sperm, that may not contain Black
Velvet, so they could then possibly still fuse with the egg and
fertilise it. But, if it happens to be the case that
the male has passed all sperm with Black Velvet in them onto the
female, these cannot fuse with the egg, so no baby is
created. So, the only risk here, in breeding two Chinchillas both
with Black Velvet in them, is that is it possible you
will not get so many babies.The positive side of it, is that obviously
by breeding two Black Velvet Chinchillas together, it
doubles your chance of getting Black Velvet babies born
from that particular couple.
Please note that these breeding combinations take in to
consideration only the colour of the coat when mating the
above combinations together. You have to also consider
other factors, when breeding these combinations to breed
a good quality Chinchilla, including density of the coat
and clarity of colour, as well as the conformation of the animals. |
