The xanthic jag carried the double recessive allele for xanthism, (xx). His mate was a wild type, so she would be homozygous (aka the same) dominant (XX). 100% of their offspring would then be heterozygous (aka different) for the xanthic trait (Xx) but appear wild type. Cross them (which has just happened) and you'll get a 3:1 ratio of wild type phenotype (what they look like) to xanthic phenotype.

The genotype (what the alleles are) on this spawn though is 1:2:1 with 25% being homozygous dominant (XX; wild type) 50% being heterozygous (Xx; xanthic carriers) and 25% being homozgyous recessive (xx; xanthic).

I love genetics. Best of luck growing the fry out. It would be a great accomplishment to introduce a new color morph to the hobby.


Indeed. Problem is you will only get 25% xanthic jags and the Xx and XX fish will be identical in appearance. However, if someone gets a male and female xanthic jag and breed them, 100% xanthic offspring is possible. I don't know how well this can be achieved cuz sometimes certain phenotypes are one sex because of sex-linked fatality and such. It will be interesting to see how this all comes out.

This is an excellent opportunity. Well done.
 
Or if you got an xanthic and crossed it with one of the heterozygous (best to use one of the breeders from this spawn, as you'd have a 50% chance with a blind pick from this spawn, or a 66% chance if you removed any xanthic fish) you'd get a 50/50 mix of xanthic and heterozygous.
 
great job man! dint kno u posted here, ill be interested in a female from that batch. ill pm you about it ok.
 
Unfortunately none of the spawn made it to free-swimming - perished as wrigglers. They did not look to even be 'wriggling' very well to be honest - oh well we shall try again...
That sucks. Youll just have to keep tryin hopefully the next batch will make it.
 
no more trys from "THIS" pair as the male passed on :(

BUT! I did sell him 2 males bred from the Xanthic so he still has a chance.
