Q1: You have a box full of objects (several thousand). One half of
the objects are cubes, one quarter of the objects are spheres,
and one quarter of the objects are pyramids. You draw two
objects out of the box. What is the probability that the first
object is a cube and the second object is a pyramid?
A: 1/8
Q2: You have a box full of objects (several thousand). One half of
the objects are cubes, one quarter of the objects are spheres,
and one quarter of the objects are pyramids. You draw two
objects out of the box. What is the probability that one of
them is a sphere and the other is a pyramid (order not
important)?
A: 1/8
Q3: Which of the following is NOT a difference between mejosis

produce?

Q5: In which circumstance would the two alleles at a locus be the
same in all circumstances? In all the other cases it is possible
for the two alleles to be different.
A: On sister chromatids before crossing over
