allotypes

Noun

allotype (plural allotypes)

1. A designated paratype of a species (or lower-order taxon) that is the opposite sex of the holotype.
   • The allotype female has one T2 deformed (fig. 75D), while the other one is normally developed.2007, Ivana Karanovic, Candoninae (Ostracoda) from the Pilbara Region in Western Australia, Koninklijke Brill, page 182
2. A genetically determined variant of the amino acid sequence of a protein.
   • Until recently, different C-region allotypes were explained by allelic genes which each encoded a different but closely related protein sequence.2007, I. D. Walker, G. Winter, D. J. Worthington, Chapter 2: Structural Investigations of Peptides and Proteins: I: Primary Structure and Chemical Modification, R. C. Sheppard, Amino Acids, Peptides...
3. An immunoglobulin allotype; the allele of the antibody chains found in an individual.
   • 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.1996, James W. Goding, Monoclonal Antibodies: Principles and Practice, 3rd edition, Academic Press, page 102
