Experimental Workflow

Dihybrid Cross Pathway

Key Steps Explained

1. Pure-breeding establishment: Prevents confounding heterozygosity in parents
2. Emasculation: Removes stamens to block self-pollination
3. Controlled pollination: Ensures known parentage of offspring
4. Large sample sizes: Statistical reliability — hundreds to thousands of offspring per cross
5. Statistical analysis: Mendel applied ratio mathematics — the first use of statistics in biology
