Verified step by step guidance

Understand the concept of X-linked inheritance: X-linked disorders are caused by mutations in genes on the X chromosome. Women have two X chromosomes (XX), while men have one X and one Y chromosome (XY). This difference in chromosome composition affects how X-linked traits are passed on to offspring.

Analyze the inheritance pattern for women with X-linked disorders: Women with an X-linked disorder have one affected X chromosome and one normal X chromosome. When they pass on their genes, they can pass either the affected X chromosome or the normal X chromosome to their offspring. This means they can pass the disorder to both their daughters and sons.

Analyze the inheritance pattern for men with X-linked disorders: Men with an X-linked disorder have one affected X chromosome and one Y chromosome. Since men pass their X chromosome only to their daughters (and their Y chromosome to their sons), they can only pass the disorder to their daughters.

Compare the options provided in the question: Based on the inheritance patterns, women with X-linked disorders pass the genes for the disorder to both their daughters and sons, while men with X-linked disorders pass the genes for the disorder only to their daughters.

Conclude the correct answer: The correct answer is 'both their daughters and sons; only their daughters,' as it aligns with the inheritance patterns of X-linked disorders.
