Mendelian Genetics Lab Background The laws of segregation, independent assortment, and dominance, discovered in the mid 19th century by Gregor Mendel, form the basis of all genetics. The ability to predict the results of crossing experiments and explain any variance between expected and observed results is still a vital part of our understanding of heredity.

Did this series of questions correctly organize each organism? Classification of Organisms The flow chart questions will lead you to the correct classification of the organisms into their respective kingdoms. Table 2, shown above, has an error in your lab manual–sunflowers do not have motility. Most of you saw the discrepancy and went with the
