text: taking a pole.....does anyone know, have or are twins and what are they? i ask this question because i have 2 year old twins a boy and a girl.  i never noticed how many twins there were until i had them.  i also seemed to notice that most twins seem to be boys, then mixed, and i rarely see sets of girls.  my twins are also fraternal, i rarely see identical.  i wanted to know what other people had noticed. my older brothers are fraternal twins, and, my family is friends with some one that has frtenal boy/girl twins. i babysit a set of identicle 2 year old boys.and i've known 3 sets of girl twins, 2 identicle and 1 fraternal.
