I have posted on this and other forums before about my yellow rat project. Basically, there are ruby-eyed albinos, red-eyed albinos, and axanthic genes all thrown in and I'm trying to figure out what is what. These were CB01 and at the time there was an obvious difference between the ruby-eyes and the red-eyes. Now, after 9 months of metamorphasis, one of the 3 red-eyed has turned ORANGE and 1 of the 5 ruby-eyed looks like it may be a red X ruby. Given that the punets say 2 types of single gene(red and ruby--1/4), one double gene(red X ruby--1/16)and one triple(orange--1/64)traits are POSSIBLE... the odds are stacked against me getting these results in 13 offspring.I ask if its posssible that with both t+ and t-, albinism is variable.I have seen Dight Goods pic of the alb. black rat with normal eyes and put a question forward--given these sets of circumstances is albinism variable??? I have asked and I havent heard of any other species that this has occured in. Anyone with any info or opinions kindly apply. This is a NEAT but frustrating project.LOL.Jeff
