Heredity B/Designer Genes C

[Epicness101]

As of now, I don't see any difference between last year's Heredity and this year's. Am I just missing something, or does this seem somewhat unfair to the incoming people who haven't done this before? Not that i'm complaining.

Some events just don't change at all between years.

Doesn't seem unfair to me, everybody had to learn it new at one point anyway. There's really nothing to change for an event like Heredity, there's no reason to change any of the content.

is the training powerpoint any good for this event? my first year competing in this event.

From my experience, the training PowerPoint and the handout are great places to learn the basics and they include essential things that should be in your notes, but you should study more advanced topics to medal. However I used the training handout at an invitational for WQ and I got fourth. It depends on the difficulty of the test. Heredity tests are usually pretty hard, and if they're easy, then the scores are very competitive, so I will advise you to take other notes just in case.

Hi, I did Heredity last year but I missed a lot of topics...luckily there wasn't much on them and I had a lot on my paper, but I still can't tell the difference between mitosis and meiosis....Ehehe... Help?

Mitosis occurs in somatic (or body) cells while meiosis occurs in sex cells (or "gametes") only.

In mitosis, each pair of identical sister chromatids, that is each X is split and goes to each side, after which the cell splits. In meiosis I, each homologous pair, that is two Xs, one from the father and one from the mother, lines up, and then one X from each homologous pair goes to each end and the cell splits. Then each daughter cell undergoes meiosis II in which now the 23 Xs line up, and they are split, and each sister chromatid goes to opposite sides of the cell after which the cell splits
Hope this helps

Is putting a codon chart on the notes a good idea? During one invite we were supplied with a chart, but I'm not sure if this would be repeated at other competitions. Have any of you been asked questions about amino acids requiring the chart without one being provided?

No one will take off any points for putting it on, so, unless you're running out of space, why not?

Mitosis occurs in somatic (or body) cells while meiosis occurs in sex cells (or "gametes") only.

Meiosis also has 2 stages, like (I'm going to use abbreviations because I'm lazy) P1 M1 A1 T1 -(another space here for G1 and stuff again)- P2 M2 A2 T2. Also, meiosis 2 (the second stage) is the same (practically) as mitosis and meiosis DOES NOT occur in gametes. It CREATES gametes. It OCCURS in germ cells.
