Question about genetics!

I am struggling to figure this out using the internet alone. I have ordered some goldfish books now, and I love genetics, so hopefully we can sort this out!

I was doing a water change and found 9 fry.


So, if I have a black moor (mother) and a calico ryukin (father), are there any substantial chances of getting a calico telescope? We would love one. :wub: Either way, the babies are well taken care of and loved.

I'd love a basics on goldfish color genetics. Thank you! :goldfish::heart

I would assume so, since one of the parent's have it. I'm not well versed in genetics (though that may change a bit thanks to Minecraft mods xP),though, so I can't tell you what the chances would be.

What is the quality of the goldfish that you have? I have not read my genetics book yet so I can't be too much help.

I can tell you form the breeders in the states that it takes quite a lot for a line to breed true. If you got these from a breeder vs. a pet shop you would be more likely to get a generation resembling the parents.

Remember that goldfish have teraploidal DNA so it's four genes from each parent. I don't think it should deter your breeding efforts just know that breeding the perfect goldfish (no matter the breed) takes decades of hard work.

Since goldfish "breeds" are determined simply by the way a fish looks, and not its pedigree, almost anything is possible. The ryukin may have telescope ancestors which would make it possible for him to carry a telescope gene. I think you should get some calicos from this cross, and probably other colors, but probably not black. As a general rule, if you cross two kinds of fancy goldfish with different mutations, the offspring will be "fantails," since most mutations are recessive.

For a number of reasons, goldfish genetics is incredibly complicated, even for a professional geneticist.
