# Probability and Punnett Squares **Independent Assortment** answers Mendel's question. **Hint:** alleles separate independently. **Mendel's Two-Factor Cross:** 1. Mendel crossed true-breeding plants: * round, yellow peas (two traits) * wrinkled, green peas 2. The offspring (F1) were all round, yellow. 3. Mendel then crossed the F1 plants. 4. He discovered some of the offspring (F2) had combinations of alleles not found in the parents. **Principle of Independent Assortment:** Genes for different traits segregate independently during the formation of gametes. This means that different traits are inherited independently from each other. **Explanation:** Different traits sort independently which explains genetic variation. Because traits are on different chromosomes.
