If the genes for the two traits are on the same chromosome, alleles for each trait will always appear in the same combinations (ignoring recombination). ![]() Independent assortment typically means the genes are on different chromosome *s. Three traits produce 8 combinations (2^3). For two traits, an individual can produce 4 allele combinations (2^2). ![]() Assuming that all traits exhibit independent assortment, the number of allele combinations an individual can produce is two raised to the power of the number of traits. Adding more traits increases the size of the Punnett Square. A single trait Punnett Square tracks two alleles for each parent.
