Learning Objectives:

3.A.1: DNA, and in some cases, RNA is the primary source of heritable information.

3.A.3: The chromosomal basis of inheritance provides an understanding of the pattern of passage (transmission) of genes from parent to offspring.

3.A.4:  The inheritance pattern of many traits cannot be explained by simple Mendelian genetics.

3.B.2:  A variety of intercellular and intracellular signal transmissions mediate gene expression.

3.C.1:  Changes in genotype can result in changes in phenotype.
