Ok - what is wrong in marrying a relative? (Page 3)

Inbreeding may result in a far higher phenotypic expression of deleterious recessive genes within a population than would normally be expected.[1] As a result, first-generation inbred individuals are more likely to show physical and health defects, including:

reduced fertility both in litter size and sperm viability
increased genetic disorders
fluctuating facial asymmetry
lower birth rate
higher infant mortality
slower growth rate
smaller adult size
loss of immune system function.

is it acceptable in pakistan?

Good question.  Where exactly DOES one draw the line?

I think maybe the general prohibition against marrying relatives may be based on the fact that it was thought to increase the chance of genetic defects.  Remember that prohibitions don't tend to be very proactive, rather, they are reactive to something already seen or experienced.

anytime i ask my friends - they just disagree and say its wrong to marry someone from your family - but no prove - i'd like to know what the problem is -  do you beleive its wrong for someone to marry his neiece? ..... do you know any law that forbids it?
