Objectives
- Students will discover how traits can be passed on from parents to offspring.
- Students will predict the traits parents will pass on to their offspring and specify how parents need to combine in order to generate a specific trait in their offspring.
Vocabulary
- allele
- genotype
- phenotype
- homozygous
- dominant
- recessive
- heterozygous
About the Lesson
In this lesson, students will gather data on traits expressed in offspring and explore how allele combinations in parents produce phenotypic ratios in their offsprings.
As a result, student will:
- Complete Punnett squares.
- Collect data on phenotypic ratios.
- Use collected data to spot a pattern in how dominant and recessive alleles are expressed.
