Here are four children in the smith family. one child has blue eyes and blond hair. the other three children have brown eyes and blond hair. how can you explain this difference in eye color?

    Human eyes offer an extensive and beautiful color palette. However, it is well known that eye color is mainly determined for genetic reasons.

   From the color of the parents' eyes to that of the great-grandparents, one can predict what color the eyes of their descendants will be. Nevertheless, you should never forget that there can always be some surprise.

   Certainly, you should know that every human being has two types of genes: dominant and recessive. Both influence the color of the eyes and hair of the individual.

   Dominant genes are the strongest, as they exert the most influence on determining the color of the baby's eyes. On the other hand, recessive genes are weaker but do not cancel each other out. This means that when chromosomes come together after fertilization, one allele will prevail over the other.

    Let's look at the case where the father has blue eyes and the mother brown eyes. In this circumstance, there would be little chance of the child having blue eyes, as the brown phenotype is dominant over blue.

In this case, both parents must have blonde hair & brown eyes & they both carry the recessive gene for blue eyes.

Father:

B b - offers dominant and recessive gene

Mother:
