Effects of apoER2 (A) and megalin (B) genotypes of d-18 fetuses on their selenium concentrations under conditions of selenium adequacy and selenium deficiency. Fetuses resulted from heterozygous matings, and the dams had been fed the respective diets for ≥4 wk before mating. Values are expressed as means with a bracket indicating 1 sd; n = 4–13. The value marked 49% in panel A was significantly different from the corresponding wild-type value by Student's t test. Other values were not different from the wild-type values within dietary groups.
