An extraterrestrial planet has organisms that reproduce with DNA the same way as organisms on Earth. A common organism dwelling on this planet have eyes that are either triangular or round. Triangular eyes (T) are dominant to round eyes (t). A Punnett square should be made to predict the offspring of two of these extraterrestrials with the genotypes TT and Tt.
What is the probability that an offspring would have triangular eyes?
To predict the probability of an offspring having triangular eyes, we need to create a Punnett square based on the genotypes of the parents: TT and Tt.
The Punnett square would look like this:
| T | T |
------------------------------
| TT | TT |
------------------------------
| Tt | Tt |
From the Punnett square, we can see that all the offspring would have at least one dominant T allele. Therefore, the probability of an offspring having triangular eyes is 100%, or 1.
