yes it isHeyey guys... just wanted to know if leaf abscission is included in the syllabus or not... well is it??
yes it is
but i saw question regarding leaf abcessionlook in the screenshot it isn't mentioned .... :O
it only mentions the role of abscisic acid in stomatal closure.
these people are just too damned confusing!!! :Obut i saw question regarding leaf abcession
when its linked to sex its X/Y, when you see homozygous/heterozygous its W^A/W^B, when you see dominant recessive its I/iHi everyone ,
I went yesterday through genetic crosses and today tried to solve some papers ,
in some questions they are using xx/xy when female/male involved and other crosses they are using crosses which involve other locus
like the question i posted below ,
any one has clue when to use xx/xy or eg use W^A /W^B ( i know this is not maths )
and can someone do the question posted below?
This question is related to sex , male and female ?when its linked to sex its X/Y, when you see homozygous/heterozygous its W^A/W^B, when you see dominant recessive its I/i
I'll go from left to right, top to bottom
key: W^A is resistant, W^B is susceptible
W^A W^B W^A W^B they must both be heterozygous because they have susceptible offspring
W^A W^B W^A W^B
W^A W^A W^A W^B W^B W^A W^B W^B now you put them the possible ways they can arrange
resistant resistant resistant susceptible only W^B W^B is susceptible because heterozygous is resistant too according to Q
u can look at the standard booklet if there is one.

For paper 4 section B, My teacher advised me : Do 2 question daily, i.e one paper write all the points in the correct order. and underline or highlight alll the important points, It will be easier for the examiner to see that u have covered up all the points, Plus explanations with diagrams. Diagrams are really very important. it carries quite a lot of marks. check wheter u have covered up all the answers as the mark schemme says. And one thing more. In part B there are many repeated questions in every paper. Mark them or highlight them U may not need to practise those agaian. u already have an answer to those questions so u may not repeat and learn from the previous answers
