1. a specimen of the opposite sex to the holotype, designated to show sexual dimorphism in a species
Usage: biology; taxonomy
2. a variant form of an antibody or other protein that differs among individuals of the same species
Usage: immunology; genetics

Examples

• The researcher designated a female specimen as the allotype to complement the male holotype.
• Sexual dimorphism in the butterfly species was documented using both the holotype and allotype.
• Scientists identified several allotypes of the immunoglobulin protein in the population study.
• The allotype showed distinct genetic variations compared to other protein forms.
• Taxonomists use allotypes to better understand species variation between sexes.
• The antibody allotype frequency varied significantly among different ethnic groups.
