Okay, I'll try to explain this as best I can.

Mouse A and B are from the same litter. Mouse A, fathered Mice C and D, to make it easier to follow. Mouse E, is a blue, and the mother of mice C and D.

Mouse A and B are both broken blacks. They had three litters together, and every single one of their babies, was a broken black. Mouse A and B, are siblings, from different litters.

Mouse C and D are from a pairing of Mouse A (male) and mouse E (female). All of the litter turned out black.

Well now, mouse C (female) has her own litter, and there are some blues in it. Which I -may- understand, because she carried blue, and the male I bred her to, has a wide genetic background, and could have possibly had blue.

But mouse D (male) was bred to a mouse which was the daughter of mouse A and an RY mouse. And there is an OBVIOUSLY blue baby in the pile!

My question here is. . . If Mouse A and B, who were both from the same parents and had three litters together, never produced blues together, why are their children producing blues, now that 1 carries blue?
There has to be blue from both sides, right? So there must be blue hiding somewhere in my Mouse aXry mouse?

That's why they call these genes recessives. :) It's just like the curly meeces that show up unexpectedly in some of my litters. I never bred for curliness, but, there it is anyway. It's a curious roll of the genetic dice, that's all.

Yep so all the offspring from the blue mouse (E?) will be atleast carrying blue so you know for sure that C and D are carrying blue. Mouse D has produced a blue baby and because blue is recessive the doe which you paired him to must also be carrying blue. Id say that as you put Mouse A to a blue and no blues were produced I think its likely that Mouse A is not carrying blue so I would imagine that the RY is carrying blue. I would suggest a test mating.

Well it must be the male that hid blue somewhere. Mouse A.
Mouse B never produced any blue. But I am planning on mating a pair of mouse A and B's offspring together, so if they produce at least one blue, I'll have my answer for sure!

It's strange that mouse B wasn't carrying blue. . . But I guess that would be the missing piece of the puzzle that makes everything make sense.

On a side note, the blue I got from mouse C, is very interesting. It's a fuzzy, but it's coat is light blue, and I want to say it may also be satin. It looks silver (not like mouse colours, but like crayon colours lol). It's a very neat looking mouse. I hope its body type is nice, I'd love to keep it around with such an interesting colour. :)

The mouse from the litter of mouse D and the RY/Mouse A pairing is just a beautiful shade of blue. :D
I hope it takes after it's father, and grandfather. They have some serious heft to them!
I'd also love for it to end up with a coat like it's father. He has a strange sort of rex coat, that is coarse, frizzy, thick, and very plush. Like velvet. :D

im confiused now as it says Mouse A and B are the parents of Mouse C and D and then later says that Mouse A and Mouse E are the parentsof Mouse C and D?

I'd say your RY is carrying blue. Thats the mostly likely conclusion however just because a pairing both carry a recessive gene doesnt mean they will definately produce a homozygous mouse. Its down to luck, although I think it would be very unusal for Mouse A to be carrying blue and not produce any blues when paired to a blue mouse although not totally impossible.

Simple. One of the original parents carried blue, but not the other original parent. That parent passed the blue gene down to both the children. ;)

Yeah. Once I wrote it out, it was a lot easier to understand. :lol:
But thinking about it, I was stumped for some reason. :p
