Considering what you know about dominant and recessive genes, what are the possible genotypes for brown eyed babies? What are the possible genotypes for blue eyed babies? Explain how you came to this response making sure to discuss dominant and recessive genes.

B = Brown, b = blue

BB & BB = 100% Brown, 0% Blue

BB & Bb = 100% Brown, 0% Blue

Bb & Bb = 75% Brown, 25% Blue

Bb & bb = 50% Brown, 50% Blue

bb & bb = 0% Brown, 100% Blue

Explanation:
