Learning Objective: When the students complete this
PPT they will be able to EXPLAIN Mendel’s
experiments and what controls the inheritance of traits.
Learning Objective: When the students complete this PPT they will be
able to EXPLAIN Mendel’s experiments and what controls the
inheritance of traits.
1. Heredity is the passing of traits from parent to
child.
 2. What are traits? The color of your hair is a trait.
 3. Scientist who study the passing of traits are
studying GENETICS.

Learning Objective: When the students complete this PPT they will be
able to EXPLAIN Mendel’s experiments and what controls the
inheritance of traits.
4. Gregor Mendel was a monk who had time to
research genetics.
 5. He did many experiments with pea plants.
 6. From these experiments he was able to determine
how physical traits are passed on to children.

A Curious Mind: Gregor Mendel
Learning Objective: When the students complete this PPT they will be
able to EXPLAIN Mendel’s experiments and what controls the
inheritance of traits.
7. Traits are controlled by GENES.
 8. ALLELES are the different forms of genes.
 9. Your traits are determined by the alleles you
inherit from you parents.
 10. Some alleles are dominant and some are
recessive.

able to EXPLAIN Mendel’s experiments and what controls the
inheritance of traits.

11. The symbol for dominant alleles is a capital
letter (e.g. “T”). The symbol for a recessive allele is
a lowercase letter (e.g.”t”).
Learning Objective: When the students complete this PPT they will be
able to EXPLAIN Mendel’s experiments and what controls the
inheritance of traits.

12. If an organism has, for the same trait, two
alleles that are both dominant or recessive, it is said
to be a “purebred”. If the organism has one
dominant allele and one recessive allele for the
same trait, it is said to be a “hybrid.”
