Answer:
Option A
Explanation:
Autosomal dominant means that even a single affected allele in genotype of offspring can cause the disease.That means one carrier parent is sufficient to pass on the autosomal dominant disease to its next generation.
Given –
Woman is taster and father is nontatster. They mate and produce a nontaster daughter.
Hence, the genotype of the parents would be
Mother – XX’
Father – Y’X
Here allele “X” represents the non taster allele while the allele “ X’ and Y’ ” represents the taster allele
Cross between XX’ and Y’X
XY’, XX, X’Y’, XX’
Thus, the parents will have a taster boy
