why do we never use DNA fingerprinting to identify your mum?

in the notes its always paternity testing.. i don't remember seeing maternity testing except in my answers. today i figured out why we dun use DNA fingerprinting for maternity testing. cos all kids belonging to this mum will have the same mitochondrial DNA! intracellular organelles are inherited from the mother and the father only contributes the nuclear DNA. so if your mitochondrial DNA is exactly the same as this woman, it probably confirms that she's your mum.. or maybe grandmum. haha

Liberation!

haha! with gp gone half my troubles were gone. with econs gone all my troubles are gone! now theres only one chem and 2 bio left... that should be pretty smooth sailing and alright.. and after that SATs. A level taking so long to finish...
i decided science A level super easy. prelims set so difficult scare us only. but arts A level very difficult. prelim and A level same standard.. so if you dunno what subject to take, just take science. its the safest. the opp cost is that u may find along the way you quite like arts subjects and you don't get to study something you like. BUT whatever it is, you still can get very safe 5A, without that much effort (i think) econs interesting but 读到要死 X_X so thus ends my 2 years of econs education lols
bio! chiong!

Wine appreciation

I'm amused. My dad loves wine. He has his own 9x2 rack for his wines. But he's the only one who drinks wine in the house. and wine is something you can only really enjoy when you have fellow wine drinking mates. unlike how u can go down beer when you're feeling lonely or just feel like destroying yourself. And because he takes quite a wide range of medicine it isn't very good for him to stress his liver out by drinking excessive alcohol. so my mum always asks us to "help him" drink so that he will have less to drink.. my mum herself isn't one who really likes to drink wine either and she'll ask to drink so my dad takes less.. today my dad got a friend to come over so that he'll have someone to drink with. lol someone who's drinking cos he's willing to drink. so for a first time in a long time he isnt drinking almost an entire bottle by himself.. lol
