IV. PROCEDURES
A. Reviewing previous
lesson or presenting the
new lesson
B. Establishing a purpose
for the lesson
What is the main role of our chromosomes
and DNA?
Do you know that some of the inherited
traits are intermediate?
What is an Incomplete Dominance?
Give examples of incomplete dominant
traits.
Recall the difference between Incomplete
Dominance and Codominant.
Is it possible for two traits to become visible
in one single organism?
Who among are aware of blood donation?
Observe the physical traits of different
organisms in the picture.
C. Presenting
examples/Instances of the
new lesson
What are the four human blood types?
Do you know how are gender are
determined?
Do you know your blood type? Are you
aware of its corresponding behavior? Let’s
check this out!
The teacher will show three Gumamela
flowers color red, white and pink. Then
he/she will draw questions out of it.
Have you ever wondered why you were
born a boy instead of a girl - or a girl
instead of a boy?

Answer Guide Questions:
F. Developing mastery
(leads to Formative
Assessment 3)

Who among the three men is the
possible father of Nathaniel? Prove your
answer through Punnett square.
2.
Who among the fathers are not
telling the truth? Why did you say so?
3.
If Nathaniel would have other
siblings, what could probably be their blood
types?
4.
In case of emergency, can his
siblings accept a type A blood? Why or why
not?
5.

woman with type O (ii) blood, will there be
possibility for them to have a blood type B
child? Prove your answer through Punnett
Square.
6.
If instead he married a woman
with AB blood type, is it possible for them to
bear child with type A and B blood? Explain
your answer.

when an egg is fertilized by a sperm that
has a Y chromosome?

to result in a female child?
3. Based on this Punnett square, what
percentage of children would you expect to

both male and female?
5. Infer which sex chromosome determines
a person’s sex.
6. What are the other factors that may
influence the expression of human
sexuality?
G. Finding practical
application of concepts and
skills in daily living
Suppose two pink-colored Gumamela
flowers are crossed in the F2 generation, is
there a probability for them to produce a
homozygous red or homozygous white
flower? Prove your answer.
Directions: Read each question carefully
and choose the statement that best
answers each question.
1. What phenotypes and phenotypic ratios
would you expect in a test cross of a pink
flowered (RW) and a
red flowered (RR) snapdragon?
a. 2 pink : 2 red
c. 2 pink : 1 red : 1 white
b. 3 pink : 1 red
d. 2 red : 1 pink : 1 white
Encircle the pictures that shows
Codominant trait.
What is the importance of knowing our own
blood type?
In what situation can it help us?
1. What are the sex chromosomes in
humans?
2. How does the sex chromosome in
human differ from male and female?
3. How many chromosomes do humans
have?
For numbers 2 and 3, base your answers in
the following problem.
H. Making generalizations
and abstractions about the
lesson
a.
b.
1. What is codominance?
2. Does codominance trait apply to human
traits? Why or why not?
In plants known as “alas diez”,
the allele for the dominant red flower color
is designated as ‘F’ and is incompletely
dominant over the allele for white flowers ‘f’.
A horticulturist allows several heterozygous
pink flowered alasdiez to self - pollinate
and collects 200 seeds.
