58. No...and genetic problems can occur from first-cousin marriage
Edited on Wed Feb-25-04 08:59 AM by jchild
The only couple I know in my home town that were first cousins before they became husband and wife have a son who is mentally retarded.

I don't know if that is the PC term, but he has serious mental retardation.

If you do the Mendelsohn square, there indeed is a GREATER LIKELIHOOD of genetic problems in these kinds of marriages.

Look at Queen Victoria's family and the prevalence of hemophilia.

Edit to add: There is a 50% higher chance of genetic disorder in first-cousin marriage than in the general population.
