Answer:
50% probability
Explanation:
During copulation between male and female the genetic component of the offspring that results is 50% of the fathers gene and 50% of the mother's gene.
If a fraternal twin married a woman and they both produce a child, the father contributes half of the genetic make up while the mother contribute half of it to make up the 100% genetic combination.
For a fraternal twin father who has a blue eye, the probability of him to transfer a blue eye color gene into his child is 50%.
