My question is what be the result of crossing the gold laced hen and silver laced rooster?
This pairing will produce silver laced chicks, but the white parts may be yellowish and not the nice clean white you want.
I would not use this pairing to produce silver laced chicks, if you want them for showing.
However, the sons will also carry the gold gene, so you could cross them back to their mother and maybe get some nice gold laced in the next generation.
Genetics of gold and silver:
Male chickens have sex chromosomes ZZ, females have ZW.
The gold/silver gene is on the Z chromosome.
Because a hen only has one Z chromosome, either she is gold or she is silver but she cannot have both genes
Because a male has two Z chromosomes, he can be gold (two copies of the gold gene), or silver (two copies of the silver gene), or he can have one copy each of the gold & silver genes (this will look mostly silver, but the white parts will be somewhat yellow looking.)
There are many genes that affect what shade of gold (red, gold, pale yellow, etc). A nice looking silver chicken will have genes that make the white look nice and clean. A "silver" chicken who had a gold parent might not look properly white, because it doesn't have the right set of modifying genes.
(A chicken that is "gold" or "silver" can also have some pattern of black markings such as lacing, spangling, columbian, etc. Or the black markings can be changed to blue or chocolate or white or some other color. But the genes for the color of the gold or silver parts work about the same anyway.)
