Question

5 a condition is autosomal recessive. the pedigree shows the inheritance of this condition in a family. which of the following is the likely genotype of individual 1? a ee b $x^{e}x^{e}$ c ee d $x^{n}y$

Explanation:

Since the condition is autosomal recessive, affected individuals have the genotype \(ee\). But individual 1 is unaffected. However, they have affected offspring. In autosomal recessive inheritance, if two unaffected parents have affected children, both parents must be carriers. A carrier has one normal allele (\(E\)) and one recessive allele (\(e\)), so the genotype is \(Ee\). Options B and D involve sex - linked notation (\(X^{E}X^{E}\), \(X^{e}Y\)) which is not relevant as it's autosomal. Option A (\(ee\)) would mean the individual is affected, but individual 1 is not.

Answer:

C. \(Ee\)
