Heamophilia is due to A) Dominant autosomal genes B) Recessive atuosomal genes C) Recessive sex linked genes D) Dominant sex linked gene
Option C) Hemophilia A and hemophilia B are inherited in an X-linked recessive pattern. The genes associated with these conditions are located on the X chromosome, which is one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is sufficient to cause the condition. Sex-linked diseases are passed down through families through one of the X or Y chromosomes. X and Y are sex chromosomes
