Predicting offspring color

I remember tables in HS for predicting offspring from 2 different plants or
parents. Hoe does it appy to a batch of Severum eggs? The female is Gold,
the male is green. Isn't it something like the 1st batch is 100% the female,
the next is 25% male etc etc?

I think it depends on the dominant gene. In this instance the dominant gene
will be green so most of the fish in a spawn will be green, followed by some
which will be a mixture of green and gold and the least number will be gold.
If you take one of these fish and breed it back to the mother then the mix
will change as it will if you breed back to the male. This is how you get
different colour combinations in the same fish.

I don't know if this will explain it better.

I wonder if the mix will always be the same with egg layers? Livebearers
seem to be mother dominant, with the father coming through more in the 3rd
batch, but they continue to carry the sperm, so that's different I think?

yeah I dont think color is a sex linked characteristic
it's a cross linked one which follow the principles of dominant/recessive
genes
