Mortality in a migrating Mennonite church congregation.

abstract：:The polymorphism of human mitochondrial DNA (mtDNA) was studied in 118 unrelated Greeks (from northern Greece) using total blood cell DNA and the restriction enzymes HpaI, BamHI, HaeII, MspI, AvaII, and HincII. One new morph was identified for MspI (named MspI morph 18Gr) and is the result of a mutation in a previousl...

abstract：:A central problem in research on twins is the estimation of the rates of monozygotic and dizygotic twin maternities. The estimation usually follows Weinberg's differential rule. According to this rule, the rate of dizygotic twinning is twice the rate of twin maternities in which the twins are of opposite sex. The mono...
