Final answer:
Mendel's law of independent assortment states that genes do not influence each other when sorting alleles into gametes. This principle can be illustrated through a dihybrid cross, such as one between pea plants with different seed traits.
Step-by-step explanation:
Mendel's law of independent assortment states that genes do not influence each other with regard to the sorting of alleles into gametes, and every possible combination of alleles for every gene is equally likely to occur. The independent assortment of genes can be illustrated by the dihybrid cross, a cross between two true-breeding parents that express different traits for two characteristics. For example, in a cross between pea plants with green, wrinkled seeds (yyrr) and yellow, round seeds (YYRR), the F₁ generation of offspring will all be YyRr.
