Answer: Assuming that the two persons carry h0m0zygous alleles, the probability of them having a child with round eyes is 0%, while the probabilty of them having a child with almond eyes is 100%
Your textbook/teacher will probably be looking for the above answer, but just incase, here's some more detail:
Let's say almond eyes are dominant (we'll symbolize them as "A") while round eyes are recessive (we'll symbolize those as "a")
AA and AA parents:
0% chance of round eyes
100% chance of almond eyes
Aa and AA parents:
0% chance of round eyes
100% chance of almond eyes
Aa and Aa parents:
25% chance of round eyes
75% chance of almond eyes
