Swordtails-Dominent gene?

Question

Does anyone know about the dominent genes in swordtails. I have one male, hes orange with a bit of black spots on his back end(no this isnt a fungus, his his natural markings). Then I have two females. One is a deep orange/red and the other is yellow with a red stipe down her side. Any idea what colors the babies will turn out?

What about the deep red/orange, should htat show up in the fry, cause I really love htat color, im looking for more in that color to breed

Answer 1

Hard to say for me,but i gotta believe that orange is dominate and yellow the recessive.This is going by the numbers of swordfish i have seen in pet stores.Seems most are the orange with black markings on lower spike,yellow i am not sure i have ever seen one before.
Really doesn't matter,without a pedigree w/ the ancestors color phase,it's all conjecture at this point. If you want yellow,but the fry are orange,breed 2 of the fry togrther.You should get at least 25% yellow offspring.
Hope this helps.

Answer 2

The fry will come out with all manner of combinations of the colorizations you have described. There will be 20 plus new fish and the colorization will depend on the parent fish of those breeding as well as the gender of the fry. If you want to know genetically how the fry will turn out, you have to work with generations of fish. You have to know the color of the great great grandparents to know for sure what the color of the newest fry will be.

The way different colorizations occur is through inbreeding. Inbreeding caused genetic mutations resulting in color differences. Color variations can also be a result of the type of food you feed. Some food professes to be a "color enhancer".

Answer 3

the genetics of your swordtail are unknown and the equivalent to a "mutt" or calico cat. The offspring will be multi-colored, and if you're interested in genetics, breeding "pure bred" guppies is fascinating!
