Which of Mendel's laws or principles explains that traits are passed from parents to offspring individually instead of as pairs, groups, or sets?

The law of segregation states that the two alleles for a trait separate when reproductive cells form, so each parent passes only one allele for that trait to an offspring. This explains why traits are inherited individually rather than as paired sets. The law of independent assortment concerns how alleles for different traits are inherited relative to one another.
