Mendelian traits in humans multiple alleles are required from each parent (co-dominant). However the Rhesus factor is truly mendelian because only one allele is inherited from each parent. Rh factor is an antigen on the red blood cell of many people's blood. A positive Rh factor is dominant (presence of antigen) and a negative Rh is recessive (lack of antigen). Blood groups that children may inherit from their parents. Mendelian traits in humans Mendelian traits in humans concerns how, in Mendelian inheritance, a child receiving a dominant allele from either parent will have the dominant form of the phenotypic trait or characteristic. Only those
