Answer:

They will all have brown eyes

Explanation:

Blue eyes is a recessive trait, so for it to manifest in the children they will have to possess the two alleles for it and on the other hand, their father possess a homozygous gene for brown eyes which is a dominant trait. When a dominant trait is crossed with a recessive trait, the dominant always shows forth phenotypically.

Lets assume the allele for blue eyes is "B" and that for brown eye is "A"

crossing a recessive trait blue eyes with dominant brown eyes will be;

Bb            x             AA

     AB, AB, AB, Ab

It is noted from the cross of the result that each child possess the dominant allele "A" for brown eyes, Thus, they will express/possess brown eyes which is dominant over blue.
