They look exactly the same as yours triscut. I only have blue tailed males in my group.
My origional thought as that they were Mpulungu.
Thanks alot to everyone! and great pics! These fish are really hard to capture on film thanks for taking the time :thumb:
I've sold some fry that were too young to tell, but that yellow tail becomes obvious pretty quickly. So, let's say I missed 5, so 15 out of 100 males (100 were likely female) isn't bad odds considering that the gene was unexpressed in my breeding group.mcorbeil said:Only 10 out of 200 had yellow tails!?! Wow i had no idea the blue tailed gene was so dominant. I hear the blue tailed males are rarer anyway :lol:
I actually have a yellow tailed female. :lol: It's yellow only when compared to the other females... very drab when compared to the males. I believe that she could be the mom of many of my YT males. I suspect that both males and females carry the gene, and since it's not particularly recessive (like albinism) it is just hit and miss depending on the particular genes each parent contributes.Do you know if the gene carried by the male, or female?
You're assuming its sex linked?triscuit said:I've sold some fry that were too young to tell, but that yellow tail becomes obvious pretty quickly.

Just for fun: I have 3 BT males, 7 females. Only 2 males bred regularly, so if one of them had the YT gene he would pass it on to half of his offspring (the other half would get his BT gene). I would get 25 YT males. So, I don't think my BT boys are passing it on. I got my ~200 fry from five females regularly (the other 2 occasionally). If 1 of those 5 females was passing on a YT gene, she would do so for half of her offspring and it would show up in half of the males: That's 200/5 = 40; 40/4 = 10 YT males.![]()
I'm not sure I understand the question. But, I'll try anyway.You're assuming its sex linked?
Where's the proof that there is a 50/50 chance? This doesn't fit the regular patterns of inheritance. Unless there has been a population genetics study of yellow tailed and blue tailed cyps it would be impossible to say for sure what the mode of inheritance demonstrates this phenotype. But I suspect that there may be a sex linked factor if there are more males with YT than females... much like Male pattern baldness or RG colour blindness.Furcifer158 said:The yellow gene is not more dominate than the blue gene nor is the blue gene more dominate then the yellow. Its just a 50/50 chance that you will get one or the other. You do have to think of this, maybe you have a blue tailed male and your breeding it with a female that has the blue tail gene that is more dominate then the yellow. You will get more blue tails then yellow. With that same goes if you have a yellow tailed male breeding with a female that has the strong yellow gene over the blue, you will get more yellow tailed males. Its too bad we can't see what the females genes are or it would be easier to predict what color tailed males you will be breeding. Also If you think of it a group of cyp's in the wild there are thousands of them so the all so mixed up, in terms of genes, that they can breed over and over with different females that there will never be a gene that is more dominate than the other. Each Cyp is different, some have the blue tailed gene that is more dominate then the yellow and visa versa. That's it
Hope it makes sense to you
