Question

watch the animation on autosomal disorders, and then answer the question. in the case of an autosomal dominant disorder, what is the probability of having an affected child if the mother is unaffected and the father is homozygous dominant?

Explanation:

Step1: Determine the genotypes of parents

In autosomal dominant disorder, the mother is unaffected, so her genotype is \(aa\). The father is homozygous dominant, so his genotype is \(AA\).

Step2: Analyze the offspring's genotypes

Using Punnett square:

	\(A\)	\(A\)
\(a\)	\(Aa\)	\(Aa\)

All offspring have the genotype \(Aa\). Since the disorder is autosomal - dominant, individuals with \(Aa\) (heterozygous) will be affected.

Answer:

100%
