Hemophilia is considered a sex-linked recessive disorder which means the disease does not occur if only one gene in a pair is abnormal.
Inheritance pattern of the offspring of a father who has hemophilia and a mother who does not have hemophilia and is not a carrier:
- all sons will be born normal
- all daughters will be carriers
Inheritance pattern of the offspring of a father who has hemophilia and a mother who is a carrier:
- 25% chance of having a hemophiliac son
- 25% chance of having a son with no hemophilia
- 25% chance of having a daughter who is a carrier
- 25% chance of having a hemophiliac daughter

Answer:
B. It allows for genetic variation.

During synapsis, homologous chromosomes exchange genetic material between one another which allows for genetic variation. This exchange is called crossing over.
