  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

  11. How do these alleles work? B B B B B b B b b b b b
