Traits and heredity
Content is AI-assisted and continuously improved through educator review
Learning Objective
Students will explore traits and heredity through guided practice and application.
In this lesson, we'll explore traits and heredity. Scientific inquiry allows us to investigate and explain natural phenomena.
Genetics is the study of heredity—how traits pass from parents to offspring through genes. Key concepts: Genes: units of heredity (sections of DNA). Alleles: different versions of a gene (brown eyes vs. blue eyes). Dominant: shows up even with one copy. Recessive: needs two copies to show. Genotype: genetic makeup (Bb). Phenotype: physical appearance (brown eyes). Gregor Mendel discovered genetic principles through pea plant experiments. Genetics explains why you look like your family and how traits are inherited!
As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
Take notes on key points and make connections to what you've already learned in previous lessons.
