which of the following explains how pregnacy can possess the combinations of traits that none of the parents possessed?

1. law of segregation
2. chromosome theory
3. law of independent assortment
4. polygenic inhertance

Law of independent assortment states that the allele pairs for different traits separate out independently during the formation of the gamete and is the explainaition how the progeny can show a combination of traits which none of the parents have.
