Final answer:
A child born to two non-taster parents would likely be a non-taster themselves since they would inherit the non-tasting recessive allele from each parent.
Step-by-step explanation:
If two non-tasters married and had a child, the chances that the child would be a taster depend on the genetics of taste perception. The ability to taste certain compounds, such as PTC (phenylthiocarbamide), is usually inherited in an incompletely dominant manner (where the presence of one copy of the allele causes a phenotype that is intermediate between the two homozygous genotypes). If both parents are non-tasters, they would likely have two copies of the non-tasting recessive allele (tt and tt), and their child would inherit one recessive allele from each parent (resulting in a tt genotype), making the child a non-taster. Therefore, in this scenario, the child would almost certainly be a non-taster as well.
