10. Mendel’s
Principle of
Heredity

11. What I Need to Know
At the end of the lesson, you will be able to:
Predict phenotypic expressions of traits
following simple patterns of inheritance.
(S8LT–IVh–18)

12. PHENOTYPE
Is the set of observable
characteristics or traits of an
organism. It includes height,
weight, eye color, skin color, and
even hair color. It is not just about
the physical traits. Behavior is
alsoconsideredasphenotype.

13. • is the study of how
traits are passed on
from the parents to
the offspring.
HEREDITY

14. GENETICS
 is the study of heredity
andvariation

16. The first person who worked on the topic
inheritance is Gregor Mendel, an Austrian
by nationality and a monk by vocation. He
worked and lived in a monastery.
He was interested in investigating how
individual traits were inherited. He wanted to
find out whether both parents contributed
equally to the traits of the offspring. He also
wanted to know if the traits present in the
offspring were produced by the blending of
the traits of the parents.

17. Mendel chose the garden pea
(Pisum sativum) for his
experiments. Are you familiar with
peas? He got interested in peas and
noted several of their distinguishing
character traits.
Why do you think Mendel
chose green peas for his
experiments?

18. Peas have traits that are
easily noticeable. They are easy
to breed and grow, which make
it easy to reproduce new
generations of peas in a short
period of time and in large
numbers.

21. 2. Identify the features that you and your family members have from the list above. Your family members
include your father, mother, brothers and sisters.
Family
Members
Type of Hair Earlobe Color of the
Skin
Hairline Dimples Handedness Nose
Questions:
1. Who among your family members look similar to you?
2. What are their similarities to you?
3. Who has the most number of differences with you?

22. What is the difference between Heredity and
genetics?
•Heredity is the study of how traits are passed on from
the parents to the offspring while Genetics is the study
of heredity and variation.

23. Why is Gregor Mendel’s discovery about
Genetics is useful to us?
• Gregor Mendel’s study and
discovery on Genetics help
us understand the
occurrence of different that
can be found in the
offspring. This discoveries
opens our minds and led to
the development of new
experimental method.
