Suprisingly we actually did this one, because our teacher tought it micght be in tha test. We used jelly snakes as chromosomes and pins to represnt the genes. I was also lucky cause they asked the same question in my trial.silvermoon said:

I didnt do this experiment so i majorly confused myself using paddlepop sticks and smarties...made me really hungry.
Yeah for the highly variable genes i spoke about introns and that 7 mark question was great!!!! I wrote about 3 full pages coz i didnt want to go overboard for 7 marks. coz 3 marks is about one paragraph.
i was happy that i new multiple alleles and polygenic inheritance coz i wrote it down then read the question and it told you! very cool.
I new it was uracil coz in my trial i guessed it and made sure i knew it this time. coz in my trial some of my yar put 'uracine' my teacher made fun of them from then on

i gave a one sentence summary of the process but it wasnt asked coz it just asked us to outline the use of highly variable genes. not the process.

i used paddle pop sticks with letters on either end, 13 paddle pop sticks, 26 letters. pulled out 2 at random, read one letter off each stick, recorded them as a match, placed sticks back in bucket, repeated till every letter had been used 3 times. observed which letter didnt ever match, assumed they were on the same paddle pop stick.Jessisbored said:

didnt have a clue about linkage experiment...so i just modelled crossing over...and labelled linked genes. I thought the questions were really not specific enough!Some of the ones in the middle section....but some of the multiple choice was a bit iffi...could have been any answer for some of them.

Good Job! Go the paddle pop sticks

Genetics: the code broken
who has "genetics--the code broken?" paper? please put on it.... Thnx

we did the linkage experiment...just with plastecine...not very exciting...but at the time the teacher stuffed it up at first and then we changed how we did it and so the whole prac was just really really confusing.....so i just went on about modelling meiosis with linked genes...
i didnt like the option very much because while the questions were broad, the testing of the topic was a bit narrow...i expected some of the gene expression/development/HOX etc to come up and human genome....why don't science exams test difficult aspects in the option?? i found my chem option (industrial) similarly stupid. I look at their questions and i think to myself - is it just me, or did i miss the point of this option? Because u dont seem to be examining the point...oh well.

witht he two graphs.... what was the answers
? im having nightmares over it

As I remember, the answer was that egg-size was polygenic and that blood-type was multiple alleles, and that while blood types are distinct from each other, sizes aren't, so in between the gram sizes there were eggs on the bellshaped curve.
