what did u guys get for the fraction question in short answer. Something like, "what fraction of offsrping will have the same genotype as parents?" something like that .. :S was it 1/4 by any chance?

yes it just asked for what proportion, either 1/4 or 25% will be acceptable

Yea iit was 1/4 i think I had to do a freaken dihybrdi cross for that! Why can't they just say number with dominant for 2 gene or something omg...

yeah the qn.. what percentage something something child same as parents' genotype, I wrote 4/16, 25%.

The fact that it specified 'female' was interesting.
It inferred to me that that answer was incorrect, and that the correct answer was I think B?

Yeah thats what made me think that 4 gametes was incorrect

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.

yeh that was pretty easy question.

omg this meiosis female question. its pretty gay . i hate it how they have 2 answers to everything.

Look at this http://www.iupucanatomy.com/images/Picture%20683.jpg
Basically they form 3 polar bodies 1 gamete.

its the proteins in the kinetochore of the centromere that create the movement

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?
