Incomplete Dominance

Incomplete Dominance. Codominance. Mendel’s experiments only looked at traits in which only one of the alleles is expressed. COMPLETE DOMINANCE. P. p. F1 x F1. P. P. P. P. p. Second Generation (F2). P. p. p. pp. Homozygous dominant = purple. Homozygous recessive = white.

  4. Mendel’s experiments only looked at traits in which only one of the alleles is expressed COMPLETE DOMINANCE a situation where neither allele dominates the other and both exercise an influence on the individual; results in partial expression of both traits. Incomplete dominance:

  6. Mendel’s experiments only looked at traits in which only one of the alleles is expressed COMPLETE DOMINANCE a situation where neither allele dominates the other and both exercise an influence on the individual; results in partial expression of both traits. Incomplete dominance: Codominance: A situation where both alleles are expressed fully to produce offspring with a third phenotype
