Example Sentences

The products of allelic forms of the same gene are known as allotypes. Allotypes are now known for all mouse heavy chains (Stall, 1995). There are no known serologically detectable allotypes of mouse κ chains.

Since different individuals of the same species may have different allotypes, these determinants can be used as genetic markers. The most common technique used for allotype determination is hemagglutination-inhibition.

Allotypes were originally defined by antisera that differentiated allelic variants of immunoglobulin (Ig) subclasses. The allotype is due to the existence of different alleles at the genetic locus that determines the expression of a given determinant.
