dihybrid cross B^P

heeeeey so yeah this post is probably gonna be pretty short cuuuuuz i dont have much to say...yeah i no i say that alot but i think this time im actually right. sooooo yeah. so we have been doing genetics and all still but we started out this new thing its like a punnett square but its like huge! it is called a dyhibrid cross i belive. i also belive i spelled that terribly wrong. so anyway at first i didnt get them like at all but i guess for this entry ill just explain that :) s0 its pretty much used to determine the likelyhood for traits like a punnet square except this is for 2 traits rather than just one. hence the word "di". so what you do is instead of putting one letter or gene in each spot you put one pair. so say you were trying to determine the chances of a kid with blonde hair and blue eyes (hey thats me!) :) so lets say the blond is recessive and blue eyes are dominant. the mom will be heterozygous for hair (well say thats Bb) and has brown eyes so lets saaaaaay ee. and daddy has blonde hair bb and and heterozygous blue eyes Ee. so a dihybrid croos looks like this obviously:

this one is filled in with some random genetic code but i thought it was a good example of what pretty much looks like. plus its color coded so yippee :)

so obviously the genotypes on the most outer edge of the picture are the genotypes the two parents and the the pairs in the circle are the different pairs that they can offer to their child. i cant remember the for it for some reason though so sorryz!
the genotypes in the boxes are all the possible genotypes for their children.
so wat you would do in our blondie stuation is first figure out the different combinations of genes each parent can offer. so since mom is Bb ee she can offer Be Be be & be OK so you put one pair to eache outer space just like in the picture except with finley you get boxes rather than circles to put them in. so you put a pair rather than just one letter like in a punnett square.
OK now the dad is bb eE so the different genotypes he can give are be be bE & bE. so put that on the other side of the dihybrid cross.
Now to determine the child just like a punnett square you do it like a graph and combine the genotypes in the boxes and record the result in the box where those match up (if that makes sense the way i said it....) so at first i though you just choose the dominant triat and put that in the box so you get a pair of two but actually you do like this, rather than tell ill just show you cuuuz im not good with directions most of the time :) ill use two of genotypes i just said there could be as an example:

bE+Be=bB Ee and you do that for all of them and you can see the genetic code for the kids nad see what they would look like--aka the phenotype :o sooo yeah there you go.

and that is my summary of the dihybrid cross :) sorry this post kinda stunk :P but watevs hughughug!

bi bi!!!
