CSSC: Chicken Smoothie Science Club

[sarcasteil]

This thread seems to be dying.. DON'T DIE!!

I really need this thread now. Considering the amount of Physics homework I'm getting.. Naw naw it's just basics, no massive stuff. Like Mass, Volume and the "p" sign.

Again.. Please don't die!

[Erille]

Really excited! My school just started a science club and I've joined the astronomy, hovercraft and bell jar projects.

[sarcasteil]

Lucky! I think mine will have some clubs in the second semester. I despise Physics, but love Chemistry [even though that means memorizing the Periodic Table] and Biology, though we haven't studied it yet.

Um... Does anyone know how to make a Punnett Square with a co-dominate and recessive traits? I can't figure it out... Thanks for any help!

[Erille]

Co-dominate being like Rr and recessive being rr? If so they you make four squares and put one letter next to or over each swaure. Then you just sort of slide the traits letters down. Like so -

Do you have a particular example of the genes involved? :3 I'm not too well versed with Punnett squares (my genetics profs all forbade using them), but I might be able to explain how the alleles interact in that situation.

As far as I know, a Punnett square works the same way with codominant traits as with any other type. Using blood type as an example, A and B are codominant while O type is recessive, so if you had AO x BO you would put those in the Punnett square like Erille shows, with A|O on the top and B|O down the side. Combine them as usual (A + B = AB, A + O = AO, O + O = OO).

The one who gets the two codominant traits A and B will express both types at the same time (they make both A and B proteins), while those with only one of those traits (AO or BO) will express that one like a normal dominant trait (they make either only A or only B proteins), and the person with the two copies of the recessive trait (OO) will show that trait (no proteins produced). The Punnett square itself is set up the same as usual. :3

All this talk of genetics reminds me of a great book called "The Violinist's Thumb." It's more or less a book on how genetics works and how it's affected society. It's written by a fantastic science writer by the name of Sam Kean, who also wrote a book called "The Disappearing Spoon," which is about the periodic table and elements. They're both absolutely lovely books.

Also, I need help with modifier genes... and incomplete dominance...

[Khisa]

Aaaah, what a read!

You promised me Mars Colonies. Instead, I got Facebook.

Yes, yes, yes. When I was 3 years old and started watching Star Trek... I dreamt of how we would once make it all come true. But programmes into space are thrown under the control of big business and money is all that counts. Market-compliant democracies instead of democracy-compliant markets have ruined us in many fields and are ruining us in many others still.

If you're regularly lost in your science classes, you need to talk to your teachers as they're obviously doing something wrong. Ask them to please explain things to you differently or forward you to media that allow you to adjust your learning to your specific learning type if the general teaching method is incompatible with you.
