This is Jack and CupCake.
And these are their kits at 2 days old. I’m taking a guess I see castor, lilac, and chocolate based kits. Some are self and some have pattern. I am honestly in hopes that one in the right picture all the way to the left is a red. Keeping fingers crossed. 😀
Here is the Punnett Square for the kits I made with Jack and CupCakes genotype based on the phenotype alone. I think this is the correct way to present a punnett square.
Ok that posted. Here goes. Ha.
This is how I understand the Letter gene series.
The A gene can only be 3 things – agouti “A”, tan “at” or self “aa”.
CupCake and Jack both have one “A” in their phenotype, the other gene is unknown – but now I have kits from them so here goes. 😯 So if one of the babies is all brown (chocolate) or a self, that would mean both CupCake and Jack need to have each contributed the “a” gene. Is this right ?
Ok, now if at least one of the kits is a self chocolate or solid color (for example) – both CupCake and Jack contributed the “a” gene meaning on the punnett square I can change both CupCake and Jacks phenotype to “Aa”. That’s how I understand it.
On to the B series. “B” black and “b” brown (chocolate) – dilute of black is blue and dilute of brown (chocolate) is lilac. Ok same thing here – if one of the kits from CupCake and Jack is brown (chocolate) then each parent had to contribute the “b” gene. This means I can change both CupCake and Jacks phenotype on the punnett square to “Bb”. That’s how I understand it.
Now the C gene, this letter series is complicated but I think I know the basics. Correct me if I’m wrong. The C series is responsible for full colors. I know CupCake and Jack are not “c” meaning REW (ruby eyed white) so no “c” in the phenotype. Also none of the kits are REW so I think it’s safe to say no “c” gene. At least so far with one breeding. Not sure what to put on the punnett square other than one “C” for both CupCake and Jack. I’m leaning toward C(chd) but I don’t know enough yet so I leave the C location alone for now.
Ok the D series is density and dilution of color. “D” dense, “dd” dilute and “Dd” dense carrying dilute. Simple enough. So if one of CupCake and Jacks kits is a lilac that means each parent contributed a “d” gene. Meaning I can change both Jack and CupCake to “Dd” on the punnett square.
And finally the E series which is responsible for extension or non-extension of color down the hair shaft. There is a whole slew of them but I figure process of elimination here. “EE” full extension of color, “ee” non extension of color, “Ee” extension carrying non extension and “enen” solid color. At this point I don’t think any of the other genes in this letter series apply – but I dunno and I’m not quite sure how “enen” fits in either with the solid color. If someone could explain that would be great. :geek:
— about this E series – I think because I see a possible red (not sure of that either) I assume I can change both Jack and CupCakes punnett square to “Ee” ? and tag onto that “en” because the possible chocolate, lilac and red appear one color – so there would have to be a solid color gene in there somewhere. Still learning all this though. 😉
So here is the new punnett square – with what I think looking at the kits. What do you think ? Corrections ?
