What is a genetic disease characterized by poor blood clotting?

Answer : The correct answer is -

Hemophilia.

Hemophilia is an X-linked recessive genetic disorder, which is primarily characterized by poor clotting of blood and abnormal bleeding.

It is mainly caused by mutation in the gene that codes for clotting factors (for instance, mutation in gene for clotting factor 8 leads to Hemophilia A, causing excessive and abnormal bleeding).

Thus, Hemophilia is the right answer.
