Genetics Question.

[SandyMushCowgirl]

Ok, now, I am wondering. If I were to breed my new HMPK to one of my girls from synirr. I figure that the HM gene would be recessive, so for F 1 all the babies would have the same tail type of the mother, but this I do not know for sure. Now, if once the babies from F 1 grow nicely and I were to breed either one of the of the females to the father, or two of the babies for an F 2 what exactly would I get? I figure there would be at least a few HMPKs. What do you all think?

Long is dominant over short.

Check the branching of the hmpk. You want *at least* 4 rays if you are thinking of crossing it to a longfin. 3 and less do not cross it to a longfin unless you want to take a step back and work through a couple of generations. Very possible you would find yourself back in VT land.

How many rays are the females? Are the females longfin or short? If they are plakats... no biggie.... 4 ray plakat female and go for it. If they are longfinned.... the more rays the better. The fry will not be plakats. The bonus to crossing a hm strain back to a hmpk is to strengthen the rays. Really important. You will notice the really well bred hm can carry their fins well past their prime.

Crossing hm strains to dt is good for expanding the dorsal and evening the anal fin.

HM happens if the genetics are there for branching. HM is just as much environmental.

If the females have less than 6 rays I would skip it (unless you know the lineage of the hmpk).... or unless you want to work with deltas & super deltas.

Just my opinion. If you have a goal.... go for it. Some of the best came from experimental crosses!

knowing what genes are dominant and ressesive, you could also use a punent square to figure out roughly what percent of your spawn will carry what genes.

I am confused. Aren't the synirr girls Plakat? (I have a bunch of females, and 2 males) That would give you all plakats. If your male carries DT, you will get some DT fry. As for the HM part, that is a little harder to predict. Is depends on genits in combo with environment. What color is the male you want to breed?

Ok, just to clear something up here, the female is a Plakat, just not a HMPK like the male. I know all the babies would be plakat's, I would just like to know how many generations/ways would the have to be bred before I would end up getting HMPK babies. I don't believe that the male has DT geno, but that I do not know.
ManyFISH4Me; The male is copper.

I think you should be able to get some HM's in F1. If not, then F2 for sure. (Wasn't the dad of the synirr babies HM?)

I think you stand a chance of getting HMs in the F1, but it's unlikely. The father and mother of my girls were both double ray, neither were HM. How many rays is your male? I'm not sure about the genetics of ray splitting (though that would be an interesting thing to study, now that I think about it,) but I believe it's a quantitative trait so it wouldn't be an easy Mendelian thing to figure out. The environment also has a lot to do with it. The female being DT geno will increase your chances of HMs, and if you select the fish with the widest caudal spreads to breed for the F2 I'm sure you could get a couple of HMS

I don't know if he was a HM or not. I don't believe so, if that was the case wouldn't we both have some HM babies?
I figured there would be some HMs in F2, but I just wanted to make sure. I've decided I'm going for both the HMPK tail and the copper color.
