Two individuals want to determine if the man is the father of a child. Below are the DNA bands of the mother and “father” after cut with specific enzymes to separate DNA. Complete the gel showing what the DNA bands of the child would look like if it were related to both individuals.
Explain why you think the gel would look like this.

Answer all questions in the lab notebook to complete the lab.
Boss Level
Children contain half of their DNA from their mother and the other half from their father. By looking at the gel we can determine which children are related to the parents if DNA bands match bands that are present in both parents. A child must have at least one matching band with both parents. If a person commits a crime, forensic scientist use the process of electrophoresis to match the suspect with DNA from evidence from the scence of the crime.
