OKAY GUYS.
WHY WOULD IT SAY 'FEMALE' IF IT WASN'T GOING TO TEST YOUR KNOWLEDGE ON THE POLAR BODIES?
It just would have said 'meiosis in humans'.
Obviously, it wants you to recognize that only one gamete is viable!

Was the gel electrophoresis 2 bands 105 60kbp?

i had one band :S i thought it said that they had no history of the disease (the one we had to label the bands for ) what did people get?

could have been to make you think in the wrong direction? people would have jumped to that conclusion.

no but its not the contraction of spindle fibres that creates the movement, its the contraction of the proteins in the centromere of the chromosome. just another quality ambiguous question from VCAA
Spindles fibres are proteins. They do contract to split contromeres.

its the proteins in the kinetochore of the centromere that create the movement
Heinemann biology 2 text book says in anaphase the spindles contract to split the contromere...that was the most appropriate answer anyway

for that I just drew one band at the 200kb bit, it was a total guess. i figured if the individual had no history of the disease, then it wouldnt move, lol :S

i had one really thick band on the 100 line because i think it said the person was unaffected and im pretty sure the disease was a recessive one. so the band asked for unaffected homozygous so i put one thick band to show two 105 pairs..anyone else?

http://www.ncbi.nlm.nih.gov/bookshelf/picrender.fcgi?book=hmg&part=A127&blobname=ch2f12.jpg

you have to download this pic. it shows female meiosis and then u get one gamete mature egg but u get polar bodies but u can see they are all haploid. those polar bodies are haploid so mabye considered gametes?
Definition of gamete is reproductive cell. Don't think thats a characteristic of polar bodies?

Wait its meant to be homozygous normal 105+60=165kbp (uncut as no restriction site) so 1 thick band at 165kbp!!!!!!!!!!

but meiosis results in four haploid cells. and it results in four haploid cells in females too.

i put a single band at 165kb, as the restriction enzyme wouldnt cut the DNA, meaning the piece is intact and is 165kb

it was polygenic. it shows continuous variation of phenotypes (i wrote)

I had two bands.
