title: Some aspects of the occurrence of new mutations in haemophilia.
abstract: Using the data available on a group of carriers of haemophilia, the mutation rate in the male germ line was compared with that of the female germ line. The mutation rate among the male germ line was about 1-2 times that in the female germ line. An assessment of grandparental ages as a factor in the production of new mutations of haemophilia was also investigated.
