My first major hands-on experience was in a university mouse genetics lab.

Herpers should understand standard genetics terms. Any who just understand the herper version will get a major shock in a general genetics high school or university course.

The URL of my favorite web genetics glossary is https://www.genome.gov/genetics-glossary. It defines "codominance" as "Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked. In codominance, however, neither allele is recessive and the phenotypes of both alleles are expressed." Two examples were provided: 1) red, pink and white flowers. 2) A, B, and AB human blood types.

I also looked for definitions of incomplete dominance, partial dominance, and semidominance. None were listed.

Red, pink and white flowers have been the traditional example of incomplete dominance. A, B, and AB human blood types have been the traditional example of codominance. Apparantly the pro geneticists have decided to take all terms involving degrees of dominance and lump them together under "codominance". Good idea, IMO. Three terms (dominant, recessive and codominant) are easier to teach than four terms (dominant, recessive, incomplete dominant and codominant).
