why when I click on page two of my peta thread does this come up???????????

I really wanna get the grasp of genetics but its seems so complicated to me I look at the links on this thread and its meant to give a basic understanding of it all in a simple way, and I feel stupid.

I suppose its taking one bit at a time if I try and learn the meanings for all the words on that first link and just as importantly the understand them so im not just rattling off something I dont understand, then that will be a good start.

You may find me asking a few stupid questions over the next few months so please bear with me.

my favourite corn morph is Ghost Bloodred corn's. they look amamzing! I really want to get a snake, but wouldnt breed them cause this whole genetics, hets, etc is way to confusing and im tight on cash since im young lol. Cornmorphs, do you sell your baby corns onto Northampton reptile centre? they always have loads of little babies in them tubs. Dan

The only stupid question is the one you didn't ask despite not knowing the answer.

Some people just take longer to pick things up than others.

I know the basic of genetics and working out double genetics - but how the hell do you do more than two? I usually use the FOIL technique but can't get my head round if there's more than two. Anybody care to elaborate?

You just have to draw a much, much bigger punnett square.

Or work it out gene pair by gene pair.

but how do you work out the breakdown of the genes?

What do you mean by "breakdown?"

When you do a normal punnett you breakdown the genes into pairs - I use FOIL but that doesn't work on anything bigger - at least I can't get my head round it. So if I want to work out something that is het for two or more things for example normal het snow,lavender x lavender, how do I do this as I understand it would look something like this AaBbLl x llll. So how do I fill in the blanks for the lack of amel and anery on the one hand, and how do I break it down to pairs of the same gene?

I don't know what FOIL means but for the example you used:

You need to consider all the possible combinations that a parent can give its offspring:

The normal het amel, het anery (I'm assuming the anery is B?), het lavender (AaBbLl) can give 8 combinations:

ABL
ABl
AbL
Abl
aBL
aBl
abL
abl

The lavender (AABBll) can only give one combination:

ABl


Therefore there is only 8 possible combinations (8x1):

AABBLl
AABBll
AABbLl
AABbll
AaBBLl
AaBBll
AaBbLl
AaBbll


Does that help?
