I have been practicing my genetics recently and have tried to work out the colour codes of all of my mice, so far I have been right with predicting three litters and am waiting for 5 more litters in the next few weeks so I can feel more confidant.
So I had a go at looking at the genetics codes of a dove tan x agouti varigated.
Dove Tans have the code:
atat B C D pp ww (most likely a she looks show line so most likely will have been a dove tan x dove tan)
( atat=non ticked or non-agouti and tan, B C and D mean full colour so not important at the moment and pp= red eyed. The red eyed part makes the mouse a dove tan, without the pp, which is recessive the mouse would be a black tan, ww=means the mouse is not varigated)
I dont know how long hair works but I think its recessive, so unless the dove tan is carrying the long hair gene which it probably isnt, all of the babies will be short haired but will be carrying the long hair gene.
Anyway the Agouti Varigated could have one of the following codes depending on what its carrying:
AA B C D PP WW (Both of his parents would have to have been black eyed, ticked (agouti) and varigated)
The babies will be;
A at B C D Pp Ww=They will all be agouti (carrying non=agouti) they will all have tan (carrying non-tan) they will all be black eyed (carrying red eyed) and all variegated (carrying non-varigated).
If the Agouti Varigated Buck have a non-ticked parent and therefore the code Aa B C D PP WW half of the babies will have the code above while the other half will still be black eyed varigated but will be black instead of agouti.
If the Agouti varigated Buck is carrying a red eyed gene from one of his parents there will also be dove tan varigated and something which has the code A at B C D pp Ww which would in theory be a red eyed agouti varigated (but I dont know if it would be called something different)
If he has only got one variegated parent whereby his code would be A B C D PP Ww only 50% of the babies will be variegated the others would be unmarked I'm guessing.
If anyone actually knows what they are talking about please feel free to correct me, and also it would be helpful if someone could point out where I went wrong. Thanks
