So remember, the probability of each one of these gametes forming is one four, because out of the four, we have four different possibilities. So each one of these has a probability of taking place with this fraction. And here we have the same exact situation one fourth, one fourth, one fourth. And so every time we cross this, each one of these has a probability of 116. So 116 for each one of these. Let's pretend that each one of these has one 16th to save time.
