lesson

(EXPLAIN)
F. Finding practical
applications of
concepts and skills
in daily living
(ELABORATE)
Give examples of traits that follow the Mendelian patterns of
inheritance.
Are all the traits controlled by a dominant or recessive gene?
What about traits that have more than two phenotypes? DO they
follow the Mendelian patterns of inheritance?
There are other patterns of inheritance and one of them is
codominance. This results when one allele is not dominant over
the other. The genetics of blood groups in humans will be used to
explain the concept of codominance.
Let the students do activity 5: Genetics of Blood Type
See attached file no. 1.
Let the students present their answers in the developmental
questions of the activity.
Give the students situational problems. Let apply what they have
learned about codominance of human blood types for them to
solve the problems.
See attached file no. 2 for the situational problems.

G. Making
generalizations and
abstractions about
the lesson
(ELABORATE)
Let the students complete the sentences related to codominance.
Present the sentences one by one.
See attached file no. 3.
H. Evaluating learning
(EVALUATE)
Given the blood types of the mother and child, identify the blood
type of the father.
See attached file no. 4.
I. Additional activities
for application or
remediation
(EXTEND)
Make a list of traits which follow the codominance pattern of
inheritance.
Read on incomplete dominance.
V. REMARKS
 Participation of the students must be 100%
 Time allotted to be discussed in the lesson must be
enough.
 Students and teacher must have a good internet
connection.
 The lesson must be interactive and have a peer-to-peer
and learner-teacher communication.

III.
Objectives
a. Predict gene combinations expected in offspring based on the genes carried in male
and female gametes.
b. Determine all possible combinations of genes for a blood type that a person might
have.
c. Explain codominance.
Materials
a. Paper
b. Pencil
Procedure
a. Blood type is determined by the presence or absence of two antigens – antigen A
and antigen B. The body’s ability to produce antigens is a trait that is inherited.
There are four possible blood types.
