11.3 Other Patterns of Inheritance
• Genes can act in various ways
1. Dominant vs. Recessive – one allele completely covers another allele.
2. Incomplete Dominance1. Definition : one allele is not completely
dominant over another
Ex: flowers – white x red flowers = pink flowers
Beyond Dominant and Recessive
3. Codominance– Definition: both alleles contribute to the
phenotype of the organism
Ex: chicken feather – black and white alleles = black and white feathers
Colors don’t blend like incomplete dominance
Multiple Alleles• Definition: more than two alleles
• (more than 2 alleles exist in a population not an individual)Ex: rabbit’s coat color
