Summary. Pedigree analysis is an important tool to assess the carrier status of the females in the families of haemophiliac patients. A study was conducted on 85 families, of which 75 were of haemophilia type A and 10 of haemophilia type B. The probability values of the females being carriers were calculated by the Bayesian method. The results revealed that 45 mothers were genetic obligate carriers and the remaining 40 probable, hence the transmission was of familial nature in 45 families, whereas the remaining 40 were categorized as isolated cases. The probability values of 425 females were calculated and a wide range of probability values ranging from 0.0295 to 1 was observed.
