The Pea's Gentic Code

Hey guys! Today is April 1st so HAPPY APRIL FOOL'S DAY! Anyway-when we came in to the class room-Ms.Caroline Schlobohm had a poster on the pea simulation and what happened in our group (Sara M. Elizabeth M. + ME!!) and what we observed. Our group had saw that the wrinkley pea gene can skip a generation. Just like us!!! If you've notices, some of the traits you have might not have come from your parents-but from the generation before your parents-GRANPARENTS!!! Then we talked about the combonation of the R and Y under the pea. Why were the letters in that specific order? Well we discovered that the children PEA's got their R and Y combo's from their parents. Well now ur saying "Well DUHHH!" but there was a pattern in which the Ys and the Rs got split amoung the children and why they were in that kind of order. Well the order is in an organized way! Its like a tree diagram and probability in SCIENCE! Math and science? Together? WOWOWOOWOWOW. Well look at the picture on the side to see how the pea's genetic info got passed from the pea's parents to the children. Just remember when you looking at this picture that the top 2 Y pairs are the parents and the bottom 4 are the children! (**When the line is drawn from one parents Y's to the other-make sure that line is the same color as the new genetic Y code below for the kids. The blue line goes with the blue code. The green line goes with the green Y code-and so on.) Well guess what? Its the same thing for the R's too!! After we were done talking about how some traits in the pea(like wrinkles) can skip a generation we talked about those funny little numbers under the yellow and green peas. What were they? What did they represent?!!?!?!?!? Well-Mr.Finley put the simulation up on the smart board and we observed from the first set of PEA's given to us! We observed that:

• Because of the way the parents are ordered the children are ordered the same way.


• All the rough pea's must have the combination of rr. There is no other combination for the rough pea gene.


• Yellow pea's have atleast one upercase Y


• Y combinations disiffer the pea's colors.


• R combininations disiffer the pea's shape.


• yy=green pea


• rr=rough pea


• there has to be atleast one upper case R for the pea to be smooth

Then we tried proving what we observed in the first part of the PEA simulation was true by breeding a yellow pea and seeing what happened. Then we started to put things together. What does meiosis have to do with this?!?!?!? How do genes and meiosis on common grounds? Well guess what?!!?!!! They are on common grounds. You need the genes to do meiosis!!!!! The Y's from the pea are in the sperm and egg cells! WOW! no way??? Haha. Well when the sperm and egg come together to make the zygote the sperm has 5o% of the DNA and the egg has 50% of the DNA. And when they come together to form the zygote its 100% in the new cell! The Y combonations from the Pea cells are the HOMOLOGOUS CHROMOSOMES!!! And the Y combonation's are like the Zygote! Look at the picture for more detail! Holy Moly Maccaroni! What a day in science!! Claudia Lucciola <3333 Round 5!
