Question: If I cross a female apterous fly with a male wild fly‚ what would the offspring look like? Hypothesis: If I cross a female apterous fly with a male wild fly‚ then the offspring will be a 50% chance of a apterous fly or 50% chance of a wild fly. If I cross a female apterous fly with a male wild fly‚ then the offspring will be a 100% wild fly.

This means that about 27% of the class were nontasters. This was expected. According to one study‚ it was estimated that “25 percent [of the world’s population] fall into the nontaster category” (Eason‚ 2007). This number is significantly less than the tasters.
