Serum electrophoretic patterns of karyotypically defined owl monkeys (Aotus trivirgatus).

Sera were electrophoretically separated and examined from 238 karyotyped Aotus trivirgatus and 29 unkaryotyped offspring. Albumin polymorphism was observed with high frequency and found to conform to a codominant allele mode of transmission. A unique alpha globulin was identified in Karyotypes I, VII and unkaryotyped offspring, of which one parent was a Karyotype I. This alpha globulin phenotype appears to be a dominant characteristic.
