Question

What is the fifth and final step in the process of drawing a pedigree chart?

Options

• Analysis: Evaluate the layout to deduce the mode of inheritance

• Layout: Assign generations Roman numerals

• Shading: Fully shade affected individuals

• Data Collection: Identify affected individuals

Answer 1

The fifth step is analysis, where the completed pedigree is evaluated to determine the mode of inheritance (autosomal or sex-linked, dominant or recessive). This critical step involves applying the 3-step shortcut strategy to identify inheritance patterns and test hypotheses about genotypes.
