How students should use this module
Read the class-data review
Review the four-gene cross, F₁/F₂ class data, epistasis, linkage, and the connection between mapping and GWAS.
Organize the real cross data
Use the class tables from your lab section, combine the relevant sepia classes, and reduce the mapping data to eight classes.
Use Tool 1: Three-Point Mapping
Identify parental, single recombinant, and double recombinant classes; determine gene order; calculate map distances, coincidence, and interference.
Test the y–m hypothesis
Use the χ² function in the mapping tool to test whether yellow body and miniature wings assort independently.
Use Tool 2: GWAS Virtual Tool
Analyze simulated human population data, calculate allele frequencies and odds ratio, run χ², and interpret the Manhattan plot.

These buttons are the same resources shown in Canvas, but organized as a single Lab 7 landing page.
1. Enter your lab section F₁ and F₂ class data.
2. Use the Three-Point Mapping tool to map y, w, and m.
3. Use the same mapping tool to test the y–m independent assortment hypothesis.
4. Use the GWAS Virtual Tool to analyze the simulated human dataset.
5. Complete and submit Assignment #7.
