Heredity B/Designer Genes C

I know that one page of information front and back is allowed on the day of the competition; however, are we allowed to put sticky notes on the page?

At rida: No. You are only allowed what you can fit on the page itself.

To answer PicturePerfect (at least on some cases):
1. At the B division level, the rules do not mention DNA fingerprints. They may be mentioned, but I wouldn't devote a tremendous amount of time to studying them.
2. For the Hardy-Weinerg problem, was there more information given? I'm not sure how one would solve this one with only this information. However, at the B-division level, there is no requirement for it on the rules.
3. I might know the differences (at the most basic level) between them (uses, basically) just in case they show up in like a vocab section or something, but I wouldn't be too concerned about them. They aren't in the rules.
4. The number of possibilities for each trait multiplied together. Like this would be 2x2x2x2x2=32.
5. That might be a rounding issue- I can't be sure without seeing it. And this is none, because the kidney shape is a form of incomplete dominance between the round and slit shape. The males only have one X chromosome, so they can't be heterozygous, and thus can't have the blended form.
6. I would assume that the C allows production of pigment, and without it, there cannot be production of the pigment. I'd make a punnet square, CcIi x CcIi. Then, because you must be ii with a C to be colored, just cross them out and count the remainder. I got 13/16 being white.

~Hope this helped! Feel free to ask me anything, this is like my absolute favorite.

Thanks! @butter side up

yes division b can bring a double sided note sheet

Can Division B participants bring a note sheet?
Speaking of notes, I heard that someone in Designer Genes wrote notes all over their arms, but I have no clue what happened to them.

Hi! I'm new to this event and I had a question about the genotype ratios:

How do you know how to order the genotypes when writing the genotype ratio? Does it matter if you label everything?

For example, if the genotype is 1 D/D: 2 D/H: 1 D/R: 4 H/H: 4 H/D: 1 R/D: 2 R/H: 1 R/R, would it matter if you wrote it as 2 D/H: 1 D/D: 1 D/R: 4 H/H: 4 H/D: 2 R/H: 1 R/D: 1 R/R?

Thanks so much in advance for your help!

Well, the tests are multiple choice (I'm pretty sure all of them are), so as long as the numbers match yours, that'll be the answer. And if there's a label, it should be labeled the same as yours. If it's not multiple choice, you should probably label it just in case. I usually label it something like:
AA:Aa:aa
2:1:1
Your way works too, but I don't know if there's any specific way to label it.

[I'm assuming you're referring to a cross with two traits here, with D as homozygous dominant, H as heterozygous, and R being recessive?]

I'm pretty sure that at least tradition (possibly also a rule) dictates that it goes in the order
DD:DH:DR:HD:HH:HR:RD:RH:RR

Such that a standard cross between two heterozygous individuals (AaBb x AaBb) would result in the ratio
1:2:1:2:4:2:1:2:1

[Also- I like the username, even if it did nearly cause me to go on a rant in the middle of the library. Violently in need of that elusive creature Season 3.]

Wow, haven't been on in a while...

Anyways, i bought one of the discs and i printed out the sample tournament (I'm doing Heredity B not Designer Genes), and now I'm looking for some more sample tests. I'm wondering if the Designer Genes material is similar enough to Heredity so I can use a Designer Genes practice test to study for Heredity.

I think they're basically the same topic, just that Designer Genes is more in-depth and difficult than Heredity. So, to answer your question, yes, you can use DG stuff to study for Heredity.
