The (F)Law of Dominance

Gregor Mendel, the "father of heredity," discovered the Law of Dominance* stating that one allele in a pair of traits is dominant over the other unless both of those alleles are recessive. This explains why the heterozygous genotype would always show the dominant allele.

But what if it doesn't?** What if sometimes the dominant allele isn't fully expressed or it has to "share" dominance? Or what if there's more than two alleles involved? Do the alleles play "rock, paper, scissors"*** to see who's dominant? Stay tuned...












 *also known as Law of Segregation or simply Mendel's Law.
**Mind blown? Read ahead - find the section titled "Complex Patterns of Inheritance."
***Good luck
