I've been breeding ASFs, but I think I want to try regular rats. Since the regular rats are a bit more complicated (rotations and such), I have some questions:

1) I understand basic genetics, but is there a site that I can go to that will break down rat genetics a little better for me...like what traits are recessive, dominant, etc. Additionally, is there a site or program or something where I can put in the phenotype of the parents and offspring and it will give me the possible genotype of the parents?

2) I'm planning to use Connie's 8 female/2 male rotation. During certain weeks, there are two or three female rats in the same male's enclosure. How do you tell the rats apart to know which week they are on? Do you just try to keep a variety of rats, like albino, hooded black, beige, etc?

3) Similarly, can you recommend two different phenotypes (for my males) that would produce different enough offspring that I should be able to make a reasonable guess about who sired them?

4) In a rat rack with medium sized concrete mixing tubs, do the just weaned rats not have a hard time reaching the water and food?

Thanks in advance!!!
