Abstract
Using some population samples of sex-linked hemophilia (A+B), the problem was examined whether the over-all mutation rate is the same in both sexes, or whether it is higher in male than in female gonads. The analysis gave the following results:
-
1.
In the series analysed sibships with only one patient are not more frequent, than has to be expected under the assumption that all mothers are heterozygous.
-
2.
Among the mothers of sporadic bleeders (hemophilia A), AHF values show the same distribution as in genetically proven heterozygotes.
Both results are strongly in favor of a higher mutation rate in male than in female gonads. However, due to some inconsistencies in the material analysed this conclusion cannot be taken as absolutely proven.
