What is the difference between incomplete dominance and complete dominance?
Complete Dominance: Where in the dominant gene completely masks the effect of the resesive gen in heterozygous conditions. Ex. Tt or Rr. Incomplete Dominance: When 2 or more alleles influence a phenotype. Ex. Flowers. Codominance: When both alleles for a gene are expressed in heterozygous offspring. Ex. Bloodtype.
What is the difference between complete dominance and incomplete dominance?
Complete Dominance: Where in the dominant gene completely masks the effect of the resesive gen in heterozygous conditions. Ex. Tt or Rr. Incomplete Dominance: When 2 or more alleles influence a phenotype. Ex. Flowers. Codominance: When both alleles for a gene are expressed in heterozygous offspring. Ex. Bloodtype.
