Re: Heredity B/Designer Genes C

I've seen tests run as both, including a recent one at regionals that was primarily a test, but had three individual stations. Three teams would go up, each to a station, and they'd do a complete cycle through them, before returning to the desks to finish the test packet. It was a very interesting w...

Re: Heredity B/Designer Genes C

THANK YOU to whoever uploaded the Wright State tests! On question 10 of station 2, "Would the protein produced from this mRNA sequence change if the A indicated by * is changed to U? If yes, indicate how," the answer key says, "Point mutation from Lys to Asn; all others remain unchanged." It seems ...

Re: Disease Detectives B/C

Now that we're in the middle of Invitational Season, I have one question: How much focus have you seen on Environmental Quality as a pose to the focus on Food-borne illness last year? Are there a lot of specific questions that have to do with with EQ, or are there more general questions about epide...

Re: Heredity B/Designer Genes C

And I'm assuming the phenotype ratio would be expressed as DD:DR:RD:RR? Yep, exactly! Should we know a little about conservative and dispersive replication? I would study the Meselson–Stahl experiment and the hypotheses behind it. It's not that much information :) And other than knowing that conser...

Re: Forestry B/C

For division C, do we need to know how trees carry out specific functions such as the Calvin cycle? I have seen some general questions about xylem, phloem, basic tree anatomy... but I've never seen anything as detailed as the Calvin cycle being asked. Oh good. I was planning on learning the Calvin ...

Re: Heredity B/Designer Genes C

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 yo...

Re: Heredity B/Designer Genes C

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...

Re: Heredity B/Designer Genes C

hi, this is my first time doing Heredity so I am kind of freaked out. Any help you could give me would be great but if you have anything about sex-linked traits.... PLEASE PLEASE HELP ME!!!!! A sex-linked trait is located on the X or Y chromosome, as PicturePerfect said. This means that it will fol...
