Mechanisme of X inactivation: hail to the Venuses!

sem lepas ade blaja pasal mechanism of X inactivation..
dalam Genetics (wa punya faveret subjek)..

tetiba bru ni dpt result ( n_n), teringt lak psl ni..
it's kind of cool to know that female have that mechanism..
the kind of, which you lower your level to get to the same level with male..
get even..
hehe..
it goes like this..

chromosomes divides into 2, autosomal n sex..
autosomal controls..ermm..kontrol semua trait kita xcept sex..(senang citer)
meanwhile sex chromosomes control our gender, primary n secondary sex characteristics..

pompuan punya sex chromosomes ade XX, laki2 lak XY..
this differences due to the male sperm donor..diorg yg tentukan jantina baby sebenarnya,
sbb Y chromosome hanya ada pada lelaki je..
diorg blh derma 2 jenis, X and Y..
pompuan limited to X je..
then, xleh salahkan pompuan yek kalo xleh baby boy..

okeh, sifat fizikal yg dikurniakan oleh Allah pd chromosomes ni adaah..
X bersifat besar dan lebih panjang, kapasiti dia pun lg byk..
maknanya thousands of genes located there..
while Y is more smaller, terlalulah keciknya
n only a few genes located there..
means that the capacity also low..eheh..
ni perbezaan diorg..

adapun lelaki punya chromosome sikit kapasiti berbanding pompuan..
sbb Y lebih kecik dr X..
jd pompuan ni kne inactive kan salah satu chromosome X dia..
utk bg sama level ngan lelaki..
erm, lebih kurang ah..
this happens during embryo..

so, if female do not inactivate one of their Xs,
what do you guys think?
memang la jd mutation..
hehe..
i just think maybe..ya know..
maybe other genes at the inactivate X,
we can use..but sure that's not gonna happens,
if it do..
mutant girl?
hurm...
....lalala...
