Incomplete dominance in flowers
WebSep 27, 2024 · An example of incomplete dominance is the flower color in four o'clock plants. 9. In both codominance and incomplete dominance, heterozygous individuals display a phenotype that is different from either homozygote. 10. Codominance and incomplete dominance are both examples of non-Mendelian inheritance patterns. WebIncomplete dominance means that neither color shows dominance in the hybrid generation. This means that instead of solid red or solid white flowers, the heterozygous plants will display a mixture of both colors. Since the entire first generation will be heterozygous for the color trait, they will all be pink (a mix of white and red).
