Do couples who are a match of two different ethnic groups have a higher incidence of miscarriages?

Does this have implications of whether or not evolution is true?Do couples who are a match of two different ethnic groups have a higher incidence of miscarriages?
I know this is going to sound weird, but I used to work in the prep room of the third largest funeral home in the US. As far as stillbirths were concerned, there did seem to be a higher incidence between some mixed couples. The higher incidences that I took note of were hispanic and caucasian and pakistani and caucasain couples. Don't know why but just thought I'd be honest and since you asked....Do couples who are a match of two different ethnic groups have a higher incidence of miscarriages?
I don't know, but they have the most beautiful children. This is true for both different races and ethnic groups. My theory is that in-breeding hurts the whole group.
no actually there is a lower chance of miscarriages then same ethnicity fetuses.
