Chapter 11 Introduction to
Genetics
Essential Question
How does cellular information pass from one generation to
another?
Chapter 11 Introduction
Section 11.1 (The work of Gregor Mendel)
• How does an organism pass its characteristics on to its
offspring?
Section 11.2 (Applying Mendel’s Principles)
• How can you predict the outcome of a genetic cross?
Section 11.3 (Other Patterns of Inheritance)
• How can interactions between alleles, genes, and the
environment affect an organism’s traits?
Section 11.4 (Meiosis)
• How does a cell divide to create cells with exactly half of the
original cell’s genetic information?

“Genetics Takes Root”
Section 11.1 The Work of
Gregor Mendel
Learning Objectives
11.1.1 Use and Describe the key vocabulary of genetics.
11.1.2 Describe where an organism gets its
characteristics from.
11.1.3 Describe the process of gamete formation and
segregation.
Experiments of Mendel
Gregor Mendel (Austrian Monk)
• In charge of the monastery garden.
• Conducted experiments with pea plants.
Experiments of Mendel
Role of Fertilization
• Pea flowers are normally self-pollinating.
• Monastery garden contained “true-breeding” plants.
• Mendel experimented with traits by crossing true-
breeders.
• Studied 7 different traits.
Experiments of Mendel
Genes and Alleles
Dominant and Recessive Alleles
Experiments of Mendel
Segregation

Advisory
Study Time.
• You should have materials from your classes to study.
• If you have nothing; I have worksheets for biology
Entry Task
What are the possible allele combinations for the parents of
a short (tt) pea plant?
• Both parents are short (tt)
• Both parents have the recessive allele (Tt)
• One parent mixed (Tt) the other with recessive (tt).

• In your notebooks make a copy of the table.
• Write a prediction of whether the traits listed in the table will
be evenly distributed or if there will be more dominant than
recessive traits.

Classroom Variation
Quick Lab (p. 311)
• Examine your feature in a mirror (or ask a friend). Determine
which traits you have for features A-E.
• Within your group record the number of each trait for your
group.
• Elect a member of your group to gather the same information
for 3 other groups.
Classroom Variation
Quick Lab (p. 311)
• Share the data with your group. Tally the number of each
allele a record in the total column.
• Complete analyze and conclude
1. Calculate: Calculate the percentage of each trait in your
total sample. How do these numbers compare to your
predictions?
2. Form a Hypothesis: Why do you think recessive traits are
more common in some cases?

Section 11.2 Applying Mendel’s
Principles
Learning Objectives
11.2.1 Explain how the principles of probability are used in
predicting outcomes of genetic crosses.
11.2.2 Construct a Punnett square to show possible
genotypes and phenotypes of offspring.
Probabilities
Probability.
• The likelihood that a particular
event will occur.

Probabilities
Segregation to predict outcomes.
• Allele segregation just as
random as a coin flip.
F2 generation contains different
combinations of alleles.
• Homozygous vs Heterozygous
p. 314
Probabilities
Genotype vs Phenotype.
• Genotype = genetic makeup
• Phenotype = physical traits
(observable)
p. 314
Punnett Squares
Punnett Squares
• Simple diagrams that use mathematical probabilities to
help predict the genotype
& phenotype combinations
in genetic crosses.
Biology Quiz
Clear off your desks.
Remember…
• No talking
• Keep your eyes on your own paper
• No electronics during the exam
When you are finished
• Check to make sure you have filled in all bubbles.
• Place question and answer sheets on the front table.
• Silently (no talking) continue reading section 11.2
