Answer
Mendel's law of segregation relates to the inheritance of alleles for a single character, while Mendel's law of independent assortment relates to the inheritance of alleles for two characters in a dihybrid cross.
Work Step by Step
Mendel's law of segregation states that each allele for a certain character will separate at gamete formation, so the alleles for a trait will each be in a different gamete (sperm or egg). Mendel's law of independent assortment states that the segregation of pairs of alleles in the gametes is independent of one another.
