Assignment: 7th grade Life Science - Genetic Variation

1. What was the purpose of the experiment?
2. What is the difference between a dominant and recessive trait?

Experimental Methods

1. What tools did you use to collect your data?
2. Describe the procedure that you followed to conduct your experiment.

Data and Observations

1. Record your observations in the data tables.

Table 1. First Generation Cross Results

Cross (B + D, C + A, or B + A)	Number of purple flowers	Number of white flowers

Table 2. Second Generation Cross Results

Cross (purple + white, purple + purple, or white + white)	Number of purple flowers	Number of white flowers

Conclusions

1. What conclusions can you draw about how sexual reproduction results in offspring with genetic variation? Add an evidence-based claim.
2. Use the simulation to observe the first-generation offspring from the cross between flowers B and D. Is it possible for either flower B or D to be homozygous dominant for the purple trait? Use a Punnett square to explain.
3. Use the simulation to observe the first-generation offspring from the cross between flowers C and A. What is the most likely genotype of flower C? Use a Punnett square to justify your explanation
