There is a lack of dominance in four o’clock plant flowers. When a red flower is crossed with a white flower, a pink flower is produced.
In an experiment, pink flowers were self-pollinated. The phenotype ratio of the offspring is

since breading the red flower with the white flower resulted in pink flower, this indicates a codominance (both alleles are expressed) in a heterozygous plant. The phenotype is deduced to RW (R for red and W for white). Self breading you are crossing RW x RW you have 4 possible outcomes, 25% of the time you'll get RR with a red phenotype, 25% of the time you'll get WW with a white phenotype, and 50% of the time you'll get RW with a pink phenotype. Try drawing out a punnet square if you're confused where the results come from!
