A tool designed to predict offspring eye color based on parental eye color uses algorithms based on Mendelian genetics. For instance, if both parents have brown eyes, the tool might predict a high probability of brown eyes for the child, while also indicating the possibility of other colors depending on the presence of recessive genes.
Such predictive tools offer prospective parents a glimpse into the potential phenotype of their future children. While not perfectly precise due to the complexity of gene interactions, these tools can be educational, illustrating basic genetic inheritance principles and the concept of dominant and recessive traits. The development of these tools reflects an ongoing interest in understanding inheritance and has evolved alongside advancements in genetic research.
