On a pedigree diagram of an X-linked recessive disorder, males and females are affected with equal frequency.Group of answer choicesFalseTrue

Analyzing the Statement

1. Understanding X-Linked Recessive Disorders:

   • In X-linked recessive disorders, the genes responsible for the condition are located on the X chromosome. Males have one X and one Y chromosome (XY), while females have two X chromosomes (XX).

2. Inheritance Patterns:

   • Males are affected if they inherit one copy of the recessive allele on their single X chromosome since they do not have a second X chromosome that may carry a normal allele.
   • Females must inherit two copies of the recessive allele (one from each parent) to be affected, making the disorder rarer in females.

3. Pedigree Analysis:

   • In a pedigree chart for an X-linked recessive disorder, the affected males would outnumber affected females. This is because a single affected X in males will express the disorder, whereas females need two affected Xs.

Conclusion

From the above analysis, it is evident that males and females do not have an equal frequency of being affected by X-linked recessive disorders. Therefore, the statement is False.

Final Answer

False
