Learning Objectives:

2.E.1:  Timing and coordination of specific events are necessary for the normal development of an organism, and these events are regulated by a variety of mechanisms.

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

3.A.2:  In eukaryotes, heritable information is passed to the next generation via processes that include the cell cycle and mitosis or meiosis plus fertilization.

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

3.C.2:  Biological systems have multiple processes that increase genetic variation.
