I was reviewing my homework, and I came across this problem that I’m not sure how to solve:
A drug, phenyl thoicarbamide (PTC), can be tasted by about 680 out of every 1000 people; others cannot taste it at all. Those who can taste it are called tasters. Those who cannot taste the drug are said to be taste-blind. Tasters have a dominant gene for the trait whereas those who cannot taste the drug have a recessive gene. An albino man who is a taster and has a taste-blind mother, marries a normally pigmented taste-blind woman whose father is an albino taster. What types of children might this couple expect?
Also, could you explain the importance of knowing what traits the parents have? How do parents pass down traits to their children?
