Question

Why are women often carriers of X-linked traits but rarely affected by them?

Answer 1

Answer:

X-linked inheritance means that the gene causing the trait or the disorder is located on the X chromosome. Females have two X chromosomes; males have one X and one Y. Genes on the X chromosome can be recessive or dominant. Their expression in females and males is not the same.

Answer 2

Because women have two X chromosomes.

Explanation:

• X linked disease means the disease is associated with the X chromosome. X linked disease can be recessive or dominant.  
• Women have two copies of chromosome and as most of the X linked to disease is recessive therefore women are often carriers of X linked disease.
• So for causing X linked recessive disease in women two defected copies if X chromosome is required but in men, only one copy is required because men have only one X chromosome.
