When does independent assortment occur, yet seem not to? Could anyone explain a situation!

Would genomic imprinting be an example?

Independent assortment is the random orientation of maternal and paternal homologues along the equatorial plane of a cell at meiosis metaphase I. If, by some quirk, all the paternal homologues lined up on one side and all the maternal on the other, then the gametes produced would carry only the DNA of the individual's father or mother, respectively, i.e. not a genetic combination of those traits. Imagine that you iteratively shuffled a deck of cards so many times that your deck ended up with cards in the same order as when you began; would anyone know that the deck was ever shuffled?

When Does Independent Assortment Occur

Indep. Assort. occurs during meiotic anaphase I,II.
1)If all the alleles under consideration were dominant, then the offspring's phenotypes would be predictable, even though independent assortment has occured.
2) Gene linkage would disrupt expected ratios in a di or trihybrid cross.
3)Small number of offspring ; not enough to show significant expected ratios.
4)Translocation of chromatids in synapsis during meiotic metaphase I.
Just brainstorming some ideas here, hopefully one or more can be used.

independent assortment occurs in Prophase 2 of meiosis.
