An instrument employing principles of heredity to estimate the probability of offspring inheriting specific iris pigmentation. These tools often utilize Mendelian inheritance patterns and known gene variants associated with ocular coloring to predict potential phenotypic outcomes. For instance, entering the parental eye colors, along with their known or estimated genotypes for relevant genes, into such a program can generate a probability distribution of likely eye colors for their children.
Such prediction models offer numerous advantages, from satisfying curiosity about inherited traits to aiding in understanding basic genetics. Historically, these estimations were based on simplified models. Modern approaches incorporate a more complex understanding of polygenic inheritance and the roles of multiple genes in determining this characteristic. This evolution has led to more accurate and nuanced predictive capabilities.
