Can you infer genotype?
If you know that dragon traits are either dominant or recessive, can you use phenotypes
of traits to infer genotypes?
Procedure
1. Select one trait card from each of
three dragon trait bags. Record the
data in your Science Journal.
2. Draw a picture of your dragon based on
your data. Label each trait homozygous
or heterozygous.
3. For each of the three traits, place one
Dragon Traits
Phenotype Homozygous Heterozygous
Green body
Red body
Four legs
check mark in the appropriate box.
4. Combine your data with your
classmates’ data.
Two legs
Long wings
Short wings
Analyze and Conclude
2. Determine which trait is dominant and which is recessive. Support your reasoning.
3. Determine the genotype(s) for each phenotype. Support your reasoning.
4.
Key Concept Decide whether you could have correctly determined your dragon’s
genotype without data from other dragons. Support your reasoning.
