Question

the genetic condition analyzed in the following pedigree could be an autosomal dominant condition.

Explanation:

Brief Explanations

In an autosomal dominant condition, an affected individual has at least one affected parent (assuming no new mutations). Looking at the pedigree:

  • Generation I: Individual 2 (affected). Her offspring (Generation II - 1) is unaffected. If it were autosomal dominant, and assuming individual 2 has a genotype like \(Aa\) (where \(A\) is the dominant allele), there is a 50% chance of passing the \(A\) allele. But the key is that in Generation III, there are affected individuals (III - 2 and III - 3). However, if we assume autosomal dominant, we can check the pattern. Let's assume the allele for the condition is \(A\) (dominant) and \(a\) (recessive).
  • Generation II - 1 (unaffected, genotype \(aa\)) and Generation II - 2 (unaffected, genotype \(aa\)) would need to pass on an \(A\) allele to have affected offspring (III - 2 and III - 3) if it were autosomal dominant, which is not possible as they are \(aa\). So it cannot be autosomal dominant.

Answer:

False
