Solution
To determine the likely inheritance pattern of a disorder based on a pedigree that shows males and females affected equally, we need to analyze the given information.
-
Understanding Pedigree Analysis: In pedigree analysis, sex-linked disorders often show a difference in the number of affected males and females. This is because males have only one X chromosome while females have two, which affects the likelihood of inheriting certain traits.
-
Equal Affects in Males and Females: Since the problem states that males and females are affected equally, this suggests that both sexes have an equal probability of inheriting the disorder. This pattern is characteristic of autosomal disorders, which are linked to non-sex chromosomes (autosomes).
-
Conclusion: Given that we see equal rates of affected males and females, this strongly indicates that the disorder is likely autosomal rather than sex-linked.
Final Answer
The disorder is likely autosomal.
