Thankyou. But God. Have you remembered the historical development of Malaria off by heart :p?
I just know Laveran and Ronald Ross reall well as they are the two most important guys for Malaria.

and for historical developments, I know the important years.

Who are all the crazy biologists we need to know?

1. Boveri
2. Sutton
3. Morgan
4. Mendel
5. Beadle
6. Tatum
7. Darwin
8. Lamarck
9. MacFarlane
10. James Watson, Francis Crick, Rosalind Franklin, Maurice Wilkins
11. Pasteur
12. Koch

Malaria guys:

13. – 1880: Laveran observed micro-organisms in fresh blood from malarial patients and suggested that malaria was caused by this micro-organisms

14. – 1886: Golgi observed asexual reproduction of microbe in blood of patients

15. – 1894: Patrick Manson proposed that malaria is transmitted by mosquitoes

16. – 1898: Grassi discovered that malaria was transmitted by the Anopheles mosquito

17. – 1897-1899: Ronald Ross established that the protozoan Plasmodium was the cause of malaria, winning the Nobel Prize.
1880- Lauran Linked causes of Malaria to a pathogen, the protozoan Plasmodium
80’s-90 – Four different species identified
1894- Manso hypothesised that mosquitoes transmit Malaria
1897- Ross proved Anopheles mosquitoes are the vectors of the Malaria pathogen
1944- Synthetic quinine developed to treat Malaria
WWII- Chloroquinnine made to fight Malaria
1950’s WHO use DDT and drain swaps to kill the vectors hoping to prevent transmission
1995- Trials to make a protective vaccine

Agreed. I don't really think they can test us with a short response, let alone a long response answer, on Burnet. Perhaps a MC question, but thats all. Its like how the Ancient Hebrews and Chinese 3000 years ago developed hygience practices. Can't elaborate further on that I suppose :S

None of the dot points led to him so, hes just in the overview of the focus area

You know Arteminisin? Its the new drug, not sure if its still new now. The syllabus doesn't seem to have it so updated, but we had this drug mentioned in the trials.

are the genes linked?
I have no idea, I don't think so :-/. I don't really understand how to do it. The answer is 9:3:3:1 if that helps (show working please)

Haha, then its not linked genes, dont worry thats only from the genetics option

Monohybrid crosses are only tested in our syllabus. :) Unless its tested in any of the option topics?

I thought there was dihybrid in blueprint

EDIT: just checked it isnt. I know its from my option Genetics the code broken

Write the phenotype ratio for this cross

BbTt X BbTt

the four possible combinations are BT, Bt, bT and bt

just do a punnet square with those 4 on the side and on top

dont ask how it works :p thats just how u solve a dihybrid

But if the genes are linked then its either

BT bt x BT bt or the genes can be linked the other way Bt bT x Bt bT and you would expect 100% parental types but this isnt always the case as crossing over can produce recombinant types with have a phenotype different to that of either parents. In a large sample space the relative position of genes on a chromosomes can be worked out by working out the percentage of recombinat types, with this percentage giving the distance between these genes on a linkage map in centrimorgans

BTW its from an option, so if you think you missed this from a core topic dont fret

okay, thats not part of blueprint for sure LOL

How is translocation related to the movement of materials in the phloem? (is that what the theory is called?)

The theory has lots of names, mass flow, mass pressure push pull etc.
Translocation refers to the movement of sucrose though a plant from is source the leaves to the "sink" for storages in fruit etc
