So...Punnett Squares...?

[kloe2008]

Is that how you guys are all coming up with these fantastic morphs?
How did you get to understand this genetics business? The basics are starting to sink in, but it's so so confusing, so are Punnett squares the answer for you guys? Or is CornCalc the way forwards....

Get and read genetics for herpers and The cornsnake morph guide. Than if theres something they don't cover, i move to punnett squares or the CornCalc.

punnet square, FOIL, etc... are good to start with. Playing with the cornsnake calc's will also help you understand more. Once you get the hang of it you don't need to use them much. I just do everything in my head. Well, I lie, I don't do the complicated ones in my head if I don't have to ( quad+ traits, hets, etc...)

The squares are a great way to start if you're working with single traits. Once you start moving into triple, quad, and quintuple traits is when it starts getting rather... well, annoying. LOL. The corncalc is a great way to get an understanding of some of the basics of the genetics, especially because it tells you the morph name, and you can click on it to get pictures!

Just to make things easy for you, the CornCalc site is linked below.

I love playing around with that site and seeing what combinations I can make with my snake and her hets

I use the branching system, which is a variant of the Punnett square that looks like a branching tree. I can do a one-locus Punnett square in my head but can get to three loci in my head with a branching system. Learned this in my university genetics class and then worked in the univ. genetics lab.

Will look into it, thanks for suggestions everyone... Anything to make it a little easier to grasp!

 

[kloe2008]

I actually have got my copy of 'The Cornsnake Morph Guide' & 'Genetics for Herpers.' I'm enthralled, and I can read them as many times as I like till I grasp it. It's bloody brilliant

I would recommend using the Punnett Square to learn how the genes work and how to figure out your clutch results, and then, once you have the working knowledge, use one of the genetics calculators when working with multiple genes that would be just ridiculous to use a square for.

Can you show this branching system? I am always at a loss when my students have a hard time with Punnett squares and I don't have any tricks up my sleeve to help them.

Unfortunately, the editor for this forum does not allow me to do a branching system. However, I posted what you want in a thread in another forum. Here's the URL:

Look for my user name (same as here) about halfway down the first page. If that still leaves you with questions, post here and I will try to answer them.

A branching system works like the predigital rotor-type odometer that used to be in cars.
