Lane 1 is a ladder, NOT an individual

• ​lanes 2-5 each contain DNA from a different individual.

• Lane 2 contains the mother of the child

• ​Lane 3 is the child

• ​Lane 4 and 5 are potential fathers

Q: Identify the individual(s) that have a piece of DNA that is 200Kb long?

​Justify your answer with data from figure 1 above

​Gel Electrophoresis

​

Figure 2 Shows 2 Ladders in Lanes 1 & 2 (these are not individuals) and 5 individuals’

DNA from 3 different populations of beavers.

​

​Justify your choice of individuals 

​

​Lane 8 has an individual from a 4th population that lives in between the populations of the individuals in Lane 4 and Lane 5.

​

Draw in the most likely pattern of DNA for the individual in Lane 8 onto the blank space in Figure 2.
