Analyzing Traits in Fast Plant Generations

In this lesson, students will explore how traits are inherited through plant generations. By the end, learners will be able to describe the processes of trait transmission and analyze data collected from plant observations. Students will count the number of purple, non-purple, and other colored plants, distinguishing between dominant and recessive alleles. Essential concepts, including genotype (inherited allele combinations) and phenotype (observable traits), will be covered, enabling a comprehensive understanding of genetic traits in plants.

Presentation Transcript

  1. Analyzing Traits in Fast Plant Generations

  2. Lesson Goal • By the end of this lesson, you should be able to describe the way that traits are passed down from one generation to the next.

  3. Collecting Data • One person from each group collect your plant dish from the light area. • As a group, count the number of purple, non-purple, and/or other colored plants that you have.

  4. Collecting Data

  5. GENOTYPE: the inherited combination of alleles (the LETTERS) Ex: Dd, BB PHENOTYPE: the inherited appearance (the physical traits you see) Ex: Dimples vs.

  6. Collecting Data

  7. Analyzing the Data

  8. Analyzing the Data

  9. DOMINANT ALLELE: the trait that always shows up in the organism whenever it is present. • RECESSIVE ALLELE: the trait that is masked, or covered up, whenever the dominant allele is present. DOMINANT RECESSIVE

  10. We use a capital letter for dominant alleles We use a lower case letter for recessive alleles How do we represent alleles? d = recessive trait D = dominant trait
