Effect of inbreeding on Wechsler intelligence test scores among North Indian children.
The effects of inbreeding in humans on the intelligence has been investigated in the present study of offspring of second cousin matings (F=0.0156, n=138 male, 132 female), first cousins once removed (F=0.03125, n=148 male, 138 female), first cousins (F=0.0625, n=161 male, 151 female), and unrelated (F=0, n=194 male, 182 female) among North Indian Muslims. The Weschler Intelligence Scale for Children (WISC-R)-74 was given to the children in the both groups. An overall significant (p<0.001) reduction of means has been observed in inbred series. The results of this study confirm the appreciable inbreeding depression especially among the offspring of first cousins.
