If we are using gel electrophoresis for establishing paternity of a baby, how will be know if someone is the father?

• The father will match the baby at any band where the baby does not match the mother.

• The father will match the baby at any DNA band where the baby matches the mother.

• The father will not match any DNA bands.

• The father will match all of the DNA bands of the baby
