Mendelian traits in human.. Skin color. The inheritance of blood groups

Most recipes non-Mendelian such as human genetics (the color of the skin - blood types)

1 - skin color:

There are included in human skin color so subject inherited skin color in humans to multiple genes where there are 3 pairs of genes control the color of human skin.

Black person AABBCC white person aabbcc and skin color depends on the number of alleles uppercase

2 - The inheritance of blood groups: Class world Landsteiner blood groups to (4) groups are A And BAB And O By the presence of antigen.

Antigen: is a protein that carries the red blood cell membrane

Blood Type	Generators antibody	Antibodies	Genetic compositions
A	A	B	I A I A Or I A i
B	B	A	I B I B Or I B i
AB	A And B	----	I A I B
O	------	A And B	ii

Inherited blood groups is subject to multiple alleles opposite as controls in the succession process (3) different alleles are as follows:
I A allele Controls the formation of antigen A
I B allele Controls the formation of antigen B
I allele Not be any generator against.
