Neoteny in humans Neoteny in humans Neoteny in humans is the retention of juvenile features well into adulthood. This trend is greatly amplified in humans especially when compared to non-human primates. Adult humans more closely resemble the infants of gorillas and chimpanzees than the adults. Neotenic features of the head include the globular skull thinness of skull bones; the reduction of the brow ridge; the large brain; the flattened and broadened face; the hairless face; hair on (top of) the head; larger eyes; ear shape; small nose; small teeth; and the small maxilla (upper jaw) and mandible (lower jaw).

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
