Hey all,

I just finished reading The Complete Boa and it has alot of great information in there since I am just getting into breeding the snakes Ive been keeping for years.

I saw how elaborate a dbl het to dbl het (Snow for Ex.) punit square can be. Does anyone have any links to triple het squares?

I was trying to construct my own but I got confused along the way. Too many letters and whatnot throwing me off haha.

I started with NaNbNc (Het for albino, Het for Anery, Het for Hypo) and was just curious on the potential outcome of a triple to triple.

Thanks,
Mike.

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.

Sir,

Thank you very much for your reply, those are both interesting sites, I will spend some time with them.

Merry Christmas,
Mike.
