Tools designed to predict offspring eye color, incorporating the complex hazel phenotype, analyze parental eye color, often considering other factors like grandparent eye color, to provide a probabilistic estimate of the child’s eye color. For example, if both parents possess hazel eyes, the prediction might suggest a higher probability of the child inheriting hazel or brown eyes, while green or blue eyes would carry a lower probability.
These predictive tools offer prospective parents a glimpse into potential inherited traits, satisfying natural curiosity. While not definitively accurate due to the intricate polygenic nature of eye color inheritance, such tools provide insight into the genetic mechanisms at play. Understanding these factors has advanced from basic Mendelian inheritance models to encompass the influence of multiple genes, expanding our knowledge of human genetic diversity.
