Set up and evaluate an expression to
calculate the probability of a
gamete having 5 paternal homologues
Draw all possible gametes that can be produced from the parent cell below
XXX X
Note: this parent cell has already undergone DNA replication
What is the probability of an
Rh+/Rh- man producing a sperm
cell with a Y chromosome and an
Rh+ gene?
Fertilization occurs when a sperm cell
and an ovum combine to form
one cell. Sperm and ova are both _____.
Not all of the cells created by females during meiosis
are used during fertilization. What are
these cells that are discarded and how many are made from one cell undergoing meiosis?
After fertilization occurs, the zygote
grows by creating more cells. What process produces these new
cells?
By mistake, an ovum has two copies of the 21st
chromosome. How many copies of the 21st
chromosome will the zygote have if the ovum is
fertilized by a normal sperm?

After DNA replication, chromosomes look like an X. The cell has __
times as much DNA as it started with.
You discover a new species. It has gametes with 27 chromosomes.
How many chromosomes do you expect to find in its
somatic cells?
Name 3 key differences between mitosis and meiosis.
One of your differences must be a drawing of metaphase
1 in meiosis and metaphase in mitosis.
