hey danoz direct, long time no speak.
its sad really, they are not on tv any more

What is the difference between random segregation and independent assortment?danz90 said:thanks for that. there are some other good youtube videos that explain meiosis well: http://au.youtube.com/watch?v=D1_-mQS_FZ0
my teacher said that remembering each phase is not necessary for our syllabus. we just need to know that in meiosis crossing over, random segragation and independent assortment occurs, and how this leads to variability in offspring.
that was pretty good.danz90 said:thanks for that. there are some other good youtube videos that explain meiosis well: http://au.youtube.com/watch?v=D1_-mQS_FZ0

from what i remember, random segregation is the way that paternal and maternal chromosomes of each homologous pair of chromosomes separate randomly, ie not all paternally-derived chromosomes go into one gamete and then all maternal into another gamete. so basically, the way that the chromosomes are arranged into haploid gametes is random.dolbinau said:What is the difference between random segregation and independent assortment?

i think you're right because i remember random segregation is a separation in the latter stage of meiosis, which is probably the last separation when it goes from 2 cells to 4 haploid gametes.danz90 said:from what i remember, random segregation is the way that paternal and maternal chromosomes of each homologous pair of chromosomes separate randomly, ie not all paternally-derived chromosomes go into one gamete and then all maternal into another gamete. so basically, the way that the chromosomes are arranged into haploid gametes is random.
independent assortment - well basically this talks about that alleles of a gene pair separate at meiosis. and these alleles are not inherited together, that is they assort independently of each other. for example, when a brown hair, blue eyed person mates with a blonde hair brown eyed person... it is still possible for a brown hair, brown eyed offspring and for a blonde hair blue eyed offspring, because the alleles for eye and hair colour separate independently of each other. so in other words, alleles of genes are not linked and separate independently of each other.
this is my understanding anyway.
ok here i go with my limited understanding...tau281290 said:Anyone do the option The code broken?
Can someone tell me what is the crrent understanding of gene expression?
my previous post on what type of questions kinda repeated throughout the past papersgloworm14 said:alot of the same questions have been popping up constantly
i suggest everyone to go over:
the work of all the major figures: mendel, pasteur+koch, beadle+tatum, watson+crick, sutton+boveri, darwin+wallace
xylem/phloem
nephrons+kidney stuff
blood+ artificial blood
adh+aldosterone
antibiotics
vaccinations
meiosis/mitosis
all the quarantine stuff
immune system
know your pathogen types
Yeah.

For the genetics option HOM/HOX/limb bud formation have never been tested in an HSC.sam2100 said:two terms for similar thing
difference not needed to be known for hsc course
sorry if this has been discussed on a page i havent looked at but:
HAS ANYONE NOTICED ANY PARTS OF THE SYLLABUS FROM PAST HSC PAPERS WHICH HAVE NOT YET BEEN TESTED AND MADE NOTE OF THEM?
if not
WHAT DID MOST PEOPLES TRIAL PAPERS SEEM TO FOCUS ON?
Crossing over occurs in Prophase which is an early stage, but I always thought Random segregation occurs in Metaphase which is after crossing over - when the homologous genes line up across the equator randomly and then 'segregate' into the two daughter cells and beyond? I don't know it can be kind of confusing.gloworm14 said:i think you're right because i remember random segregation is a separation in the latter stage of meiosis, which is probably the last separation when it goes from 2 cells to 4 haploid gametes.
crossing over is in the early stage.

I dont think malaria has been asked in an HSC paper (although Ive seen it in some trials), neither has modelling pasteurs experiment

they've asked to give cause/symptom/prevention/control/elimination etc on ONE infectious disease [i would've used malaria] in a past papermidifile said:For the genetics option HOM/HOX/limb bud formation have never been tested in an HSC.

um yeah awesome explaination. i dont think we need to know the difference for this course though do we? i mean as far as we're supposed to be concerned, random segregation=independent assortment?
I dont think theyd specifically ask you "what is the difference between independant assortment and random segregation" but they might give you a diagram and say "what is happening here" and if you say the wrong one they might mark you down.bekmay said:HAHA 'mates'. it sounds funny talking about people mating.

wtf how fast did u finish search for beter health!gloworm14 said:i like to call it 'making love'
study update: im up to the last point of search for a better health.
communication next.
