A member asked:
Is there a risk in marrying a 2nd cousin once removed or is the gene pool dilated enough with such a distance?
A doctor has provided 1 answer
No detectible risk: over that of the general population. Population geneticists determined many decades ago that French Canadians were all the equivalent of second cousins. Founding effect is the cause of most ethnic-related increased chance of being a carrier of a rare genetic variant--present among the people founding a population, expanding over a several hundred years. Prenatal tests adjust for ethnicity
