What percentage of babies have Brown and Blue eyes?
-Dominant- [34]

20 babies were born in the ward, 10 of them had blue eyes and the other 10 had brown eyes.

% of blue eyes babies is 50% and % of brown eyes babies is also 50% (10/20*100).

<h3>What is a Dominant trait?  </h3>

               

Brown eye color gene is a dominant trait, and it can express itself in  pure breed  condition as well as impure breed condition.

Blue eye color gene is recessive and can only express itself in pure breed recessive condition, the dominant gene repress the expression of the recessive gene phenotypically, but the genetic makeup remains the same.    

Hence, the blue-eyed babies have pure breed recessive genotype and brown eyed babies have pure breed   dominant genotype or    genotype.
