Many visible human traits that exhibit high heritability were included in the older McKusick's Mendelian Inheritance in Man. OMIM (Online Mendelian Inheritance in Man) is a comprehensive database of human genotype–phenotype links.
Common violations of the Mendelian model include incomplete dominance, codominance, genetic linkage, environmental effects, and quantitative contributions from a number of genes (see: gene interactions, polygenic inheritance, oligogenic inheritance). Very few phenotypes are purely Mendelian traits. Offspring with either one or two copies of the dominant allele will display the dominant phenotype. 2 Human traits with probable or uncertain simple inheritance patternsĪccording to the model of Mendelian inheritance, alleles may be dominant or recessive, one allele is inherited from each parent, and only those who inherit a recessive allele from each parent exhibit the recessive phenotype.
