All of the chromosomes in the cells of the children contain genetic information from just one of the parents.
Half of the chromosomes in the cells of the children contain genetic information from one parent, and half of the chromosomes contain genetic information from the other parent.
Some of the chromosomes in the cells of the children contain genetic information from each parent, but the number of chromosomes containing information from each parent cannot be predicted.

Disciplinary Core Ideas: LS3.B In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent. These versions may be identical or may differ from each other.
