How my school teaches Genetic Cross Diagram...

For anyone staring at this too long: Phenotype Genotype(s) Note Green bb only b is a recessive allele, needs two copies Blue Bb or BB B is a dominant allele, needs just one Mike aa only a is a recessive allele, needs two copies Sully Aa or AA A is a dominant allele, needs just one

i posit mikeness is only partially dominant with sullyness and thus the chart is wrong (needs more inbetweens)

what would a Mike/Sully codominant hybrid look like though

smaller, more legs
