Yes *daylia* my knowledge of genetics does stretch as far as knowing that it takes two to make babies, even though both parties need not be present at the conception ☺
I was illustrating a point and not writing a thesis.
As it is unfortunately the girl who has to carry the can, I would hope that they would try to be more responsible, in the face of the typical irresponsibility of my own sex.
It is not all due to the UK habit of providing housing for single mothers, that young single girls have babies, although if one believes the scare stories in the gutter press it is quite prevalent.
Giok ☺
