This is a brief video I made that shows how genes can be passed on through 3 generations. You can see by the colours how much or how little of the grandparents can be passed on to the children. It is true that there are WAY more than 8 genes that get passed on, but it is a mistake to think that we always inherit EXACTLY 1/4 of our genes from each grandparent. The farther down the line we go, the more the //actual// percentages can vary.
