Nature of Science:
10.1.NOS: Making careful observations- careful observations and record keeping turned up anomalous data that Mendel’s law of independent assortment could not account for. Thomas Hunt Morgan developed the notion of linked genes to account for the anomalies
10.2.NOS: Looking for patterns, trends and discrepancies- Mendel used observations of the natural world to find and explain patterns and trends, Since then, scientists have looked for discrepancies and asked questions based on further observations to show exceptions to the rules. For example, Morgan discovered non-Mendellian ratios in his experiments with Drosophilia.

Objective:
- Describe the trends and discrepancies that led Morgan to propose the idea of linked genes
- Describe the experiment of Bateson and Punnett that lead to results that did not support Mendel’s law of independent assortment.
- Describe the trends and discrepancies that led Morgan to propose the idea of linked genes.
