Genetics and Inherited Traits

This lesson, aimed at fifth graders, covers the basics of heredity, including inherited traits, instincts, and learned behaviors. It explains how traits are passed from parents to offspring, using examples from both humans and animals. The lesson also introduces Gregor Mendel's work on heredity, detailing his experiments with pea plants and the discovery of dominant and recessive traits. Finally, it discusses how pedigrees can be used to trace inherited traits within families.

What is heredity?

• The process of learning new skills

• The behavior of animals in the wild

• The passing of traits from parents to offspring

• The study of plant growth

Which of the following is an example of an inherited trait?

• Learning to ride a bike

• Having blue eyes

• Knowing how to cook

• Playing a musical instrument

What is an instinct?

• A behavior an animal is born with

• A skill acquired through practice

• A botanist who specialized in plant diseases

What did Mendel discover about traits?

• They are only passed from mothers to offspring

• They are controlled by two factors, now known as genes

• They cannot be traced through generations

• They are not influenced by the environment

What is a dominant trait?

• A trait that is less common

How are dominant and recessive traits represented?

• With pictures and diagrams

• With capital and lowercase letters

• With colors and shapes

• With numbers and symbols

What is a pedigree?

• A chart used to trace the history of traits in a family

• A method for training animals

• A tool for measuring plant growth

• A type of genetic mutation

How are males and females represented in a pedigree?

• Males with circles and females with squares

• Males with triangles and females with circles
