What little I have read about koi genetics, there does not seem to be much knowledge about it.
I read an article in one of my koi books about a simple study that was done.
It suggested white koi bred to white will produce white offspring. White to yellow- the yellow will be the dominate color. Yellow to orange and orange will be the dominate color. These were solid color koi. When you get to Kohaku, sanke, etc they stated it gets more complicated with possibly more colors appearing in a spawn.
I bred some butterfly koi this spring.
2 Females:
Platinum gin rin
Yellow and white (hariwake) gin rin
3 males:
yellow gin rin
orange gin rin
orange and white gin rin
I did not take extraordinary efforts to save all the offspring. So many were eaten by siblings and predators. I later culled the deformed. I probably have somewhere around 100 left. Some appear to have good possibilities.
I had expected mostly gin rin. Apparently gin rin is not dominate. Less than 1/2are gin rin.
I had no ugly colors. All fry are the same colors as the parent fish.
I do seem to have a much higher percentage of long fin fry than what I see reported from long fin spawns done by some others. My guess is less than 5 % with regular fins and even those may be longer fins than normal as they grow.
I only have 2 that are platimum at this point. The majority are yellow. The second highest number are hariwake (mostly yellow and white). I only have a couple of orange gin rin and a few orange and white (gin rin and wagoi).
I will try to count percentages when I move them to larger pond for winter.
I just thought some one might find this interesting as I did.
Any one else have any observations about their spawnings and genetics?
