Gold and SIlver crosses can be difficult at times, but following this chart can help you keep control of future offsprings colour.

Breeding a gold male over a silver female will give you a different result than breeding a silver male over a gold female. 

Females can only carry one copy of gold (s+) or silver (S) therefore they can only pass that copy of the gene onto their male offspring.

1) Gold male over Silver female (Sex-linked cross).

Breeding a gold male (s+/s+) to a silver female (S/-) will result in gold females (s+/-) and GOLDEN males (s+/S) (they carry one copy of gold and one copy of silver). These boys however will appear silver at hatch, so you can easily tell boys from girls.

​

2) breeding Silver male over Gold female.

Result of this breeding is silver female (S/-) and GOLDEN males (S/s+). However, these males appear silver at hatch just like the females, so you wont be able to separate by gender until they've grown up and other distinguishing features can be seen.
