Paternity test gel: mother, child and two possible fathers

An example figure from the Gel Electrophoresis generator.

A pale blue agarose gel with blue bands in five lanes labeled Ladder, Mother, Child, Father 1 and Father 2; the 1 kb ladder is labeled from 10,000 bp to 500 bp, and each other lane has four bands — A 1% agarose gel in blue, as a classroom DNA stain leaves it, with a 1 kb ladder labeled from 10,000 bp to 500 bp in the first lane. The other lanes hold DNA from a mother, her child and two possible fathers, four bands each. Every band of the child’s must come from the mother or the father, so students match the child’s bands to decide which man is the father.
