Which of the following shows the correct match of the box numbers and the genotype of the offspring?

Technically a biology question but if you create the chart all 4 types will be Tt because the Male has the genotype of TT so they will each have a large T in each box (like making a multiplication table). and the female has tt so the only possibility is a large T with a small t in all four squares because there are both homogenous genotypes.  (the bottom-most answer is the correct answer)

The answer is 10. and if you go by pemdas you would 1. multiplication 2. division 3. addition 4. subtraction
