Quizplus · Accepted Answer

The genes of a child have the least in common with the genes of a grandparent because only 25% of the child's genes come from each grandparent, whereas 50% of the child's genes come from each parent and siblings and fraternal twins share a varying degree of genetic similarity depending on how many genes they inherited in common from their parents.
