Answer:
It is possible if 1 or both parents have the blue-eyed recessive allele
Explanation:
It works both ways.
B=Brown-Eyed Dominant Allele
b=Blue-Eyed Recessive Allele
Solution 1:
Bb x Bb
Using a Punnett Square (You can look up "Punnett Square calculator" online to find an example) you can find that there is a 25% chance for BB alleles in the offspring, 50% chance for Bb, and 25% chance for bb.
This shows it's possible for an offspring to have blue-eyes.
Solution 2:
BB x Bb
Using a Punnett Square you can find that there's a 50% chance for BB alleles in the offspring and a 50% chance for Bb.
This shows that it's possible for an offspring to have blue-eyes.
