Severum Genes - Colors

[chrisb01]

I have a male Green Severum and a female Gold Severum. They have laid eggs about four or five times. I got to save a couple of the batches. I have nineteen from the first batch and about fifty or sixty from the second. The new batch are still tiny, pinheads.

The first batch I saved is already about dime size. However, they all seem to be throwing towards the Green color, none of them Gold.

Can this happen?

Could a Green male and Gold female produce only Green offspring?

If gold is a recessive gene then both parents would have to carry the gold gene for you to get gold fry. That means if the green fish is 100% green then all the fry will be green, but they will carry recessive gold genes. If those fry grow up and breed with each other or to another gold severum, a percentage of those resulting fry will be gold.

If you green did not have any gold genes in it, then yes. The green would be dominate so without a recessive gene it could not express itself.
