What is the difference between a dominant color allele and a recessive color allele found in pea plants? Responses Both alleles code for proteins that produce pigments. The pigments produced by a recessive color allele are white. A recessive color allele codes for proteins that produce pigments. A dominant allele does not code for those proteins. A dominant color allele codes for proteins that are involved in the production of pigments. A recessive color allele does not produce a working version of these proteins. Both alleles cannot code for any proteins. Purple is the natural color of plant petals when no other factors are involved.​
