On an extraterrestrial planet, which had organisms that reproduced with DNA the same way that organisms on Earth do, green little organisms have eyes that are triangular or round. Triangular eyes (T) are dominant to round eyes (t). A Punnett square was made to predict the offspring of two of these extraterrestrials with the genotypes Tt and tt. Use the Punnett square below to answer any questions that follow.

According to the Punnett square, what is the probability that an offspring would have triangular eyes?

a
0:4
b
1:4
c
2:4
d
3:4
e
4:4
