Yes, Mr. and Mrs. Miller's children can be born with brown eyes.
Eye color is determined by genetics, specifically by multiple genes. Brown eye color is typically dominant over other colors, such as blue or green. If both parents have brown eyes, they could either be homozygous (BB) or heterozygous (Bb).
- If both are homozygous (BB), all their children will have brown eyes.
- If both are heterozygous (Bb), there is a chance for some children to inherit the recessive allele (b) and be born with blue or green eyes.
To summarize, the children's eye color depends on the genetic makeup of the parents, but it is definitely possible for them to have brown eyes.
