Cousin Marriage Print E-mail

Dr. Kennedy Everyone carries rare recessive alleles, rare genes that are generally innocuous in the heterozygous state but that in the company of another gene of the same type are capable of causing an autosomal recessive disease. We are all reservoirs for genetic disease. First cousins share a set of grandparents. So for any particular allele (gene) in the father, the chance that the mother inherited the same allele from the same source is 1/8. Further, for any gene the father passes to his child, the chance is 1/8 that the mother has the same gene and ½ that she transmits that gene to the child so 1/8 X ½ = 1/16. Thus, a first-cousin marriage has a coefficient of inbreeding of 1/16. First cousins, if they marry, should not have biological children, but rather consider adoption.
