Question

When many families were tested for their ability to taste the chemical PTC, the parental pairs were grouped into three types and the progeny totaled. The results were as follows

Parents	# of Families	Tasters	Nontasters
Taster x taster	425	929	130
Taster x nontaster	289	483	278
Nontaster x nontaster	86	5	218

Assuming that PTC tasting is dominant (P) and nontaster is recessive (p), how can the progeny ratios in each of the three types of matings be accounted for?
