It's the same as a dihybrid cross, but is considered a trihybrid cross since there are three mutant traits. It's time consuming and tedious which means mistakes are easy, but take a look here: www.science.oregonstate.edu/bi10x/otherresources/punnett squares.htm

The best thing to do is use the Genetics Wizard. www.geneticswizard.com/f_start_genetics_wizard.asp

You would pick three since you have three mutant alleles. Enter the names of the traits in the boxes: hypo, anery, albino and choose heterozygous for all three unless it is a known super hypo. Since both parents are the same do the same thing for the male and female. It's a great tool once you get the hang of it. I don't check the D or C boxes for codominant or dominant either as you know what hypo is so you know what its going to look like if it is heterozygous or homozygous and I find the little superscripted letters to be distracting.
