Answer:
bb, bb, Bb, Bb
Explanation:
Brown eyes are a domininat (B) gene whilst blue eyes are recessive (b). In order for the children to have blue eyes, both parents must contain the recessive genes for blue eyes. This means that the father had mixed genes (Bb) for blue and brown eyes but due to the dominant brown gene has Brown eyes. The mom has blue eyes meaning that she has the recessive gene pair for blue eyes (bb). When the pair's genes are mixed. Bb+bb. Mendelian gene crossing occurs and the offspring have a 1:2 chance of inheriting either blue or brown eyes due to the gene mixture that resutls and is shown in the answer above.
