1
An asterisk (*) is a wildcard; it signifies that any gene for the group
could be present
and still result in the designated phenotype. |

We have produced these beautiful fish by crossing a chocolate leopard
(+/+ Z/Z +/+ +/+ Sm/Sm) with a double black double zebra (B/B Z/Z).
The cobra has been previously defined as +/+ Z/Z +/+ +/+ Sm/+ grown
with a long photoperiod. We prefer to define a variety by appearance
and discuss separately the genetic and environmental variations that
can be used to produce the variety. This is because 1) it is possible
to produce the same phenotype with more than one genetic combination,
and 2) environmental conditions producing a given phenotype can vary
between hatcheries. In this case, the cobra phenotype was produced without
a long photoperiod.

Marble Leopards can be produced with the following genetic combinations:
(M/+ Z/+ */* */+ Sm/+) (M/+ Z/Z */* */+ Sm/+) (M/+ Z/+ */* */+ Sm/Sm)
or (M/+ Z/Z */* */+ Sm/Sm). Our Marble Leopards are usually M/+ Z/+
*/* */+ Sm/+.
