Abstract
The incidence and the factors that influence twinning were studied in six villages of Dholka Taluka, a rural field training centre. The twinning rate was 10.10 per 1000 maternities. The monozygotic and dizygotic twinning rates were 4.53 and 5.56, respectively by applying Weinberg's differential formula. In three fourths of the twin births, both twins were of same sex while in one fourth, they were of opposite sex. The twinning rates increased significantly with increase in parental age and pregnancy order of mother.
