How does incomplete dominance differ from incomplete penetrance?

#Unit 8. Inheritance Biology
  1. Incomplete dominance refers to alleles at the same locus; incomplete penetrance refers to alleles at different loci.

  2. Incomplete dominance ranges from 0% to 50%; incomplete penetance ranges from 51% to 99%.

  3. In incomplete dominance, the heterozygote is intermediate to the homozygotes; in incomplete penetrance, heterozygotes express phenotypes of both homozygotes.

  4. In incomplete dominance, the heterozygote is intermediate to the homozygotes; in incomplete penetrance, some individuals do not express the expected phenotype
