The idea that chromosomes orient themselves randomly during metaphase I is Independent Assortment. This leads to more combinations of genes.
Explanation:
During metaphase I, the pair of chromosomes align in the plate of the cell. In this step, the independent assortment takes place.
The independent assortment is the distribution of different genes into two gametes, is independent, because the distribution of the different genes, does not influence the distribution of the other genes. The independent assortment leads to new combinations of genes from the parental and maternal side, resulting in offsprings that do not look exactly like their parents.
