Hey there, Biology rockstars! 🌟 Are you ready to dive into the intriguing world of incomplete dominance and codominance? We promise you, it's more fun than a barrel of DNA! 🎉 So let's unravel these genetic phenomena.

Key Definitions 📚

  • Incomplete Dominance: When neither allele is dominant and the offspring's phenotype is a blend of the parent phenotypes.
  • Codominance: When both alleles are equally strong, and both alleles are visible in the phenotype of the hybrid organism.

Real-world Example for Codominance - ABO Blood Group 🅰️🅱️

You know how some people have AB blood type? That’s not some middle ground between A and B. Nope, it’s like the blood cells are shouting, "Hey, I’m BOTH A and B!" It's like being ambidextrous but for your blood. That's codominance for you!

Real-world Example for Incomplete Dominance - Mirabilis jalapa Flowers 🌸

Imagine you mix red paint with white paint. You get pink, right? That’s exactly what happens in the flower Mirabilis jalapa. If you cross a red-flowered plant with a white-flowered plant, the babies will be pink! Awww... It’s like the plants couldn’t decide, so they went for something in between.
