The dominant allele is expressed and the recessive allele is masked. This is an example of complete dominance. In heterozygous relationships where neither allele is dominant but both are completely expressed, the alleles are considered to be co-dominant. Co-dominance is exemplified in AB blood type inheritance.

A son of the 1977 Triple Crown winner Seattle Slew, Swale was trained by Woody Stephens and ridden by Laffit Pincay, Jr., both now members of the National Museum of Racing and Hall of Fame. Swale's dam, the stakes winning mare Tuerta, was born with one eye. Her name means one-eyed in Spanish.
