If father of a baby is hemophilic and mother is a carrier then chances if the baby inheriting the disease will be:
Correct answer: B. 50%
- A. 0%
- B. 50%
- C. 75%
- D. 100%
Explanation
If the father is hemophilic (has the disease) and the mother is a carrier, the chances of the baby inheriting the disease will be 50%. This is because there is a 50% chance that the baby will inherit the hemophilia gene from the father. Therefore, the correct option is '50%' as there is a 50% chance of the baby inheriting the hemophilia gene and having the disease in this particular situation. Options 0%, 75%, and 100% are incorrect as they do not accurately represent the genetic inheritance patterns of hemophilia in this scenario.

About X-linked Recessive Inheritance
X-linked recessive inheritance involves genes on the X chromosome, so males express a recessive allele with no corresponding allele on their single X chromosome, while females may be carriers. Pedigrees cover haemophilia and red-green colour blindness, including carrier mothers, affected sons and the absence of father-to-son transmission.
