How can we explain inheritance patterns that do not follow simple Mendelian genetics? 1. Incomplete Dominance 2. Co-dominance 3. Multiple Alleles.

Exceptions to Mendelian Genetics Some alleles are neither dominant nor recessive, and some traits are controlled by multiple alleles or multiple genes.
Chapter 13: Extensions of Mendelian Principles: Multiple alleles Modifications of dominance relationships Gene interactions Essential genes and lethal.
Chapter 11-3: Exploring Mendelian Genetics. To determine if the segregation of one pair of alleles affects the segregation of another pair of alleles,
Unit: Mendelian Genetics. For example: ◦ Some alleles are neither dominant nor recessive. ◦ In most organisms, the majority of genes have more than two.

Patterns of Inheritance. I. Simple inheritance (Mendelian inheritance) One gene controls the trait There are two versions (alleles) of the gene One allele.
Non Mendelian Genetics - WordPress.com · What do you mean, non-Mendelian? • Each gene had only two alleles. • One allele was always dominant. • Each trait had two opposing
