. (This is a true story). At a college fair, the biology department was using PTC paper to demonstrate dominant and recessive phenotypes. A married couple with a baby came up to the demonstration. The husband and wife determined they were both non-tasters. The husband put a strip of PTC paper into the baby's mouth and he made a face and spit it out. To see if it was just paper the baby didn't like, the husband gave the baby a regular piece of paper with no PTC on it. The baby happily sucked on the plain paper. The husband gave the baby another piece of PTC paper, and the baby spit it out immediately and began to cry. A while later the couple was seen with the wife crying and the husband yelling. • Do you think the husband is the father of the baby? Why or why not? Use a Punnett square to back up your answer.
