Exceptions to Mendelian inheritance definitely add some excitement to our understanding of genetics! While Mendel's rules taught us about dominant and recessive traits, real-life genetics can be a bit more complicated.
Let’s explore some of these interesting concepts:
Incomplete Dominance: This happens when neither one of the genes completely hides the other. A great example is snapdragons. When you cross a red flower with a white flower, you get pink flowers!
Codominance: In this case, both genes show up equally. Think about human blood types: type AB blood has both A and B markers at the same time.
Multiple Alleles: Some traits come from more than just two genes. Take the ABO blood group for example. It includes three types of genes: a, b, and i, all competing to decide your blood type!
Polygenic Inheritance: Some features, like skin color or height, are influenced by many genes. This leads to lots of different appearances.
These exceptions show us that genetics is wonderfully complex and goes beyond just simple dominant and recessive traits!
