All partially right answers. Red blood cells contain no DNA so there is no difference. white blood cells on the other hand do contain DNA, depending at which level you wish to pitch your answer.
white blood cells inherit DNA in the usual manner.
regulation of the DNA in the white blood cells will be very different between father and son, MHC for instance is expressed as a haplotype (either all the paternal or all the maternal alleles are expressed.

Half of the son's DNA is from his father. Half of the DNA is from his mother.

Very similar, you get half from your Father and half from your Mother. That is why DNA is used to determine if someone is related and how.

blood has no DNA since red blood cells have no nucleus to hold DNA.
