Final answer:
In biology, a daughter can be affected by an X-linked recessive disease only if she inherits the disease allele from both her carrier mother and her affected or carrier father.
Step-by-step explanation:
The subject of the question is Biology, specifically genetics and the inheritance of X-linked recessive diseases. When considering X-linked recessive diseases, if the mother is a carrier and the father is unaffected, daughters have a 50% chance of being carriers themselves but are generally not affected because they receive a normal X chromosome from their father. However, a daughter can be affected by an X-linked recessive disease if she inherits the recessive gene from her mother and her father is also a carrier or affected by the disease and provides an X chromosome with the same recessive gene.
