One of two or more different genes that may occupy a specific locus on a chromosome "an
alternate form of a gene" - ANS Alleles

A silent gene; a gene that does not appear to produce a detectable antigen such as Jk, Lu, O -
ANS Amorph
Sequence of DNA that is inherited; an individual's actual genetic makeup - ANS Genotype
Produced by the genotype, including an enzyme to control a blood group antigen; and the
length of long bones of the skeleton (what you see) - ANS Phenotype
A trait or characteristic that will be expressed in the offspring even though it is only carried on
