I'm in a debate with someone about the offspring of a sunglow to a normal. I say it will produce 50% het albino and 50% hypo, he says it will produce ALL het albinos and half of those are hypos. Who's right?

np

there are two pairs of genes involved. A sunglow has a pair of albino genes and a pair of genes made up of a salmon (hypo) gene and a normal gene. The normal has a pair of normal genes where the sunglow has a pair of albino genes and a pair of normal genes where the sunglow has a salmon and a normal gene. By the way, the normal version of the albino mutant gene is not the same as the normal version of the salmon mutant gene.

All of the babies get an albino gene from the sunglow and a normal gene from the normal. That means that all of the babies are heterozygous albino.

Half of the babies get a salmon gene from the sunglow, and the other half of the babies get a normal gene from the sunglow. All the babies get a normal gene from the normal. That makes half of the babies salmon and the other half normal (meaning not salmon).

Put it together, and you find that all of the babies are heterozyous albino, and half of the babies are also salmon (hypo).

Hope this helps.

Can't usually add to Pauls responses as they're always good...but, I thought it should be mentioned that your hypos will be what's termed DH Sunglows(Hypo/salmon het albino) just in case that helps make sense of everything for you. Take care
