1)The allele responsible for the Siamese coat-color pattern produces an unstable tyrosinase enzyme. This type of gene product is an example of what type of allele?

2) Determine which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but more closely resembles one homozygous phenotype than the other?

A. epistasis

B. codominance

C. incomplete dominance

D. complete dominance

E. incomplete penetrance
