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

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?

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
