Answer 1

Answer:

Explanation:

As the disease is autosomal dominant, hence, the male parent who is normal must have the homozygous recessive genotype i.e., aa. The affected female can have either Aa or AA genotype.

If the genotype is M, all-the progenies will surely be diseased but if the genotype is Aa, then there is a 50% chance of having normal offsprings. But unfortunately the couple has produced only affected progeny and each of them must have the genotype Aa.

So, the correct answer is 'Aa, aa'.

Answer 2

The affected individual have Aa genotype.
