COMPLETE AND INCOMPLETE DOMINANCE.
Mendel happened to choose characters that showed complete dominance,
e. the dominant trait completely masked the recessive one in the F1 generation.
In man, certain characters are inherited in the same way
g. colour of the skin; normal colour is dominant to albinism (lack of skin pigment).
The children are all normal but have the gene for albinism.
Such individuals are referred to as carriers.
