Unraveling Genetics: Exploring Gregor Mendel's Discoveries

Unraveling Genetics: Exploring Gregor Mendel's Discoveries

Learning Objective

At the end of the lesson, you will be able to explain the principles of inheritance and apply them to pedigree and Punnett squares.

What do you already know about Gregor Mendel and his contributions to genetics?

Introduction to Gregor Mendel

Gregor Mendel, an Austrian monk, is known as the father of modern genetics for his work with pea plants, which led to the discovery of fundamental principles of inheritance.

Principles of Inheritance

Mendel's experiments revealed the principles of segregation, independent assortment, and dominance, providing the foundation for understanding genetic inheritance.

What is the name of the Austrian monk known as the father of genetics?

1. Thomas Hunt Morgan
2. Gregor Mendel
3. Charles Darwin
4. Alfred Russel Wallace

Pedigree Diagrams

Pedigree diagrams are used to trace the inheritance of genetic traits within families over multiple generations.

What is a genetic disorder caused by a mutation in a single gene?

1. Turner syndrome
2. Down syndrome
3. Hemophilia
4. Cystic fibrosis

In human genetics, what is a pedigree used for?

1. To understand plant genetics.
2. To study bacterial genetics.
3. To trace the inheritance of a specific trait.
4. To analyze protein expression.

What is the purpose of gene mapping?

1. To determine protein structure.
2. To locate and identify genes on a chromosome.
3. To analyze RNA splicing.
4. To study cell division.

Punnett Squares

Punnett squares are a visual tool used to predict the possible genetic outcomes of a cross between two individuals.

If a heterozygous tall pea plant (Tt) is crossed with a homozygous tall pea plant (TT), what is the probability of their offspring being tall?

1. 50%
2. 100%
3. 25%
4. 75%

Research Task: Mendelian Genetics

Students will conduct research on a specific genetic disorder or trait and present their findings to the class, highlighting the inheritance pattern and potential impact.

Conclusion and Recap

Summarize the key concepts learned about Gregor Mendel's contributions to genetics, pedigree diagrams, and Punnett squares.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
