Can anyone explain Triples to me?

yeah, i posted this out before i finally got a grasp on it :) thanks

When looking at those punnet squares, you are only concerned about those particular genes. (No extra chromosomes/genes popping up, at least none that I'm aware of) The thing is that the other genes are considered 'normal' so of no interest. When you are interested in more than one gene, then you have more variables and a greater amount of combinations are possible, hence the ever increasing punnet square. :D

man all this triple/quad stuff hurts the brain. i just think like this,
get a visual morph you like
find another morph you think will look good with it
breed the two together
raise the babies
breed the babies
keep breeding until you see a diffrent morph come out!

Now that Im finally understanding this stuff I might make a website that lets you enter the genetics of the male and female and have it dynamically create a punnet square with the possibilities, as well as a database containing all of the known combinations with names.

http://www.geneticswizard.com/ oops... looks like it's already been done. :) It's a pretty cool aplet... and there's a downloadable program that you can add new genes and new alles and all kinds of stuff. Kinda nifty..... Freeware RULES!

the internet is always one step ahead of me :)

LOL - Yup... It'll do your triple/quad questions for you... but the results are a bit confusing... and it's debateable if it's accurate or not. :)

Doesnt look too debatable to me...looks like an awesome tool.....maybe I am missing something..but it looks to me like it gives the theoritical probablities of each genotype exactly......there just happens to be a lot of genotypes when you cross a triple het x triple het. or a quad het x quad het

IF you drew out the square they would be huge.......a trip het x triple het would require a an 8 x 8 square (the number of possible gamete comboinations is 2^n where n is the number of gene pairs--For a triple het, n=3 so 2^3=8)

For a quad het x quad het you'd need a 16 x 16 square.

Has anyone actually introduced an interesting triple recessive morph to the market?

Another useful in genetics is the pedigree chart.....these are probably more useful in many ways than punnet squares for organism that dont produce tons of offspring like humans, mice, or balls.....

A free online pedigree drawing program is available at http://www.progeny2000.com/students/

I've used it a lot to make genetics problems for students.....it takes a little time to get use too and the export functions are a little cumbersome....but it works...

I am taking Biology in college now and this is the best explanation that I can give.....
If you have double hets and bread them together you will come out with 9 different possible reconnections of the genes (recessive), and there will be a varying degree as to which each of these reconnect. For instance if you breed a Double het ghost and albino to a double het ghost and albino you would draw the punnit square as this [AG, Ag, aG, ag] x [AG, Ag, aG, ag] because these would be the possible gene reconnections. And from there you would attemp to get the aagg through backcrossing and what not.... Now you would want to take the double homozygous and breed it to a homozygous of another gene, say pied, and from there you would come up with 100% triple hets. Now it gets more complicated because you would want to cross the triple hets together so your Punnit square would be this [PAG, PAg, PaG, Pag, pAG, pAg, paG, pag] x [PAG, PAg, PaG, Pag, pAG, pAg, paG, pag] with 64 outcome boxes and 27 possible recombinations. 12.5% would be Trip Hets, 1.6% would be triple homozygous and 1.6% would be normal. Only 4.8% would show one recessive trait without being heterozygous for another. 18.75% would show one trait and hold one other as heterozygous. 18.75% would show one trait and be double heterozygous. 4.8% Would be double recessive without another hetero trait, and 9.375% would be double recessive with one hetero trait. 9.375% only tetero for one trait. 18.75% double hetero and 12.5 triple hetero...

I hope that i didnt mess up the math because i am doing other things while doing this. Also I am new and this class actually got me into snakes again since I used to have balls when I was younger, pre-navy. Anyways just wanting to know how people think I should start off a project with 1000-1500 dollars. I will make a new thread if you want to answer me there...
