animals’ fur, hair, skin or

then those exhibit co-

Study the
following examples of co-

1. Human MN Blood
Group
There are several blood
group systems
discovered by experts.
One of them is the MN
blood group. This blood
group in human beings
exhibits co-dominance. M
and N are antigens found
on the surface of the
human red blood cells.
This group of antigens is
There are three alleles
responsible for this blood
system: IA
, IB
, and i. The
absence and presence of
antigens in the blood
determines the person’s
blood type. There are
only two antigens, the A
and B. Individuals with
blood type O do not have
antigens in their blood
because allele i does not
code for an antigen.

the additional activities.
A.Polygenic inheritance
is another non-
Mendelian pattern of
heredity. Research the
following about polygenic
inheritance.
1. What is polygenic
inheritance?
2. Give examples of
traits that show
polygenic inheritance.
3. Solve this problem
below that involves
polygenic inheritance.
Problem: Skin color is
one of the traits in human
which is determined by
polygenic inheritance
system because it is
possibly involving as
many as 9 genes. To
make this simple, let us
consider the influence of
2 genes: A and B., where

dark skin color is
dominant. Suppose a
man who is AABb
marries a woman who is
Aabb, what would be the
genotypes of their
children. Prove your
answer by using a
Punnet square.
