Genetics is the study of heredity :

Sex-Linked Genes and Pedigrees. Linked Genes Some genes are linked because they are on the SAME chromosome. A chromosome is a set of linked genes. Remember:

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.

Advanced Genetics.

Incomplete Dominance, Codominance and Sex-Linked Traits

Exceptions to Mendel’s laws. 1) Incomplete dominance Some alleles are not completely dominant and the offspring will have a “blending” of the parents.

Genetics Complex Patterns of Inheritance. Incomplete dominance Neither trait is dominant over the other. A third phenotype is observed that is a combination.
