Beyond Dominant & Recessive Alleles Some alleles are neither dominant nor recessive, and many traits are controlled by multiple genes.

Genetics Rules Rule #1? Rule #2: Incomplete dominance some alleles aren’t completely dominant so they BLEND Rule #3: Codominance some alleles dominate.

Incompletely Dominant Allele When two different alleles are both dominant over another allele, but not dominant over each other. An example is a cross.

Mendel and the Gene Idea · Dominant vs. Recessive Alleles • The third concept is that if the two alleles at a locus differ, then: • One allele (the dominant allele) determines

Modern Genetics. Multiple Alleles More than two alleles can be inherited –Example: Blood Types –Alleles= I A, I B, i Blood Type (Phenotype) Type of Antigen.
