With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 

You do each PCR reaction on chromosome 15 and load each one into a separate well of an agarose gel, and then run the gel.

 

 

Match the babies up with their actual parents.

 

BABY	PARENTS
I. Baby A	a) Father and Mother #1
II. Baby B	b) Father and Mother #2
III. Baby C	c) Father and Mother #3

P, Q, and R are three different inbred, true-breeding strains of mice. A hybrid between P and Q is mated to R, and a hybrid between Q and R is mated to P. A male from the first mating is mated to a female from the second mating. What is the inbreeding coefficient of their progeny?
