Is Hemophilia A Nondisjunction?
Hemophilia is inherited in an X-linked recessive pattern. A condition is considered X-linked when gene mutation that causes it is located on the X chromosome, one of the two sex chromosomes. In males (who have only one X chromosome), one altered copy of the gene in each cell is enough to cause the condition.
Is Hemophilia A chromosomal abnormality?
Hemophilia is caused by a mutation or change, in one of the genes, that provides instructions for making the clotting factor proteins needed to form a blood clot. This change or mutation can prevent the clotting protein from working properly or to be missing altogether. These genes are located on the X chromosome.
What chromosome number is hemophilia on?
Hemophilia C stems from mutations in the F11 gene, which is found on chromosome 4. Each person inherits two copies of F11 regardless of gender, meaning that the disorder affects males and females equally.

Although most adults won’t grow taller after age 18 to 20, there are exceptions to this rule. First, the closure of the growth plates may be delayed in some individuals (36, 37). If the growth plates remain open past age 18 to 20, which is uncommon, height could continue to increase. Second, some suffer from gigantism.
