SQUARES

This page will hopefully help out any of you who are not exactly sure how the Punnett Square works?........There are so many different combos to write up.......that it seems endless!!..........Inside of each "solution" page........I will have the "genetics master" version/outcome of what the square is telling us............and I also will do a little write-up for each one in more easy to understand terms........once you figure out that all simple recessive traits work the same...........you can replace what ever simple trait you want to in the square...........meaning that any simple recessive trait like Albino or Piebald will show the same results in the square............your just using a different mutation........real simple example..........HET X HET......no matter what simple recessive gene is involved, will produce in 4 eggs...........1 homozygous ( example: albino that is yellow and white with pink eyes)............2 heterozygous ( example: het albino which are completely normal looking, but carry the albino gene ).........and 1 normal ( example: this snake looks normal like the 2 heterozygous clutch mates ).........so HET X HET will always produce homozygous offspring and normal looking offspring that is 66% possible het for the trait...........why 66%???..........because 1 of the 3 normal looking babies is not carrying the gene............that normal baby is the 33% that makes this so much fun!!!!!!!!!!!!

Some of these squares are going to be harder to understand than others..........it takes a while for it all to sink in...........but once you start to understand the "rules"........you will be doing the "results" in your head.....:)........I still get confused and have to see it on paper sometimes...........and now that we are working with double hets, triple hets, dominant and co-dominant mutations........and mixing them all up............who knows if there is really an answer that the square can even give us??............"odds are odds".........there is good luck..........and there is bad luck.........I for one have proved the square wrong each and every year I breed...........so lets all have fun with it........and not worry too much about "what we should produce because the square tells us so"..........and just enjoy the breeding and the "not knowing everything all of the time"..........Mother Nature knows no boundaries..........especially when we are fortunate enough in the ball python hobby to give her so many colors to work with.........the possibilities are endless!!!!!!!!

I will explain in better "dummy"detail on each "solution" page..........also, I do have some good "rants" on the "Ralph's Words" page about Hets and Possible Hets........that really dig deep into the subject...

Take notice to the first entry ( Heterozygous X Heterozygous )........inside that link is a WORLD of information on how a square works..........it is going to be the most in depth example of how the square works, it is the simplest square to learn on...........so you can refer back to it for other solutions as you get hooked on genetics..........and eventually turn pro.....:)

The links in "Yellow" are active........I will slowly but surely get the rest of the links done and then some................

ENJOY!!!!!!!
