 Look at the Punnett square.
If the two parents represented in the Punnett square have four offspring, what does the Punnett square tells you? 

• Two of the offspring will definitely have the genotype Aa.
• It is more likely that two of them will have the genotype Aa than the genotype aa.
• There is a 50% chance for each of the four offspring to have the genotype Aa.
• It is less likely that two of them will have the genotype Aa than the genotype aa.
