The Research Question
For our brassica plants, we researched the
plants’ height. Some of us breeded the two
tallest, while others in our group tried other
things with height. Our research led to our
hypothesis.
Our Hypothesis
• We hypothesized that if we bred the two
tallest plants, a tall plant would be
produced, unless if the plants were
heterozygous and the children received
the recessive genes.
Background Information
Scientific name: Brassica Rapa
Common name: Field Mustard, Common
Mustard, and Rape Mustard.
Kingdom: Plantae
Family: Brassicaceae
Class: Magnoliopsida
Background Information cont.
• The average time that it takes for a Brassica
Rapa plant to grow is approximately 35
days.
• Brassica Rapa is pollinated using a bee as
its vector.
Our Experimental Method/Design
• For our experimental method/design, we
placed the Brassica seeds in containers
using wicks and containers with water. The
water would feed through the wicks and
give water to the plants. We fertilized the
plants once a week, every Friday. We
placed these containers in light boxes in
place of sunlight.

Pollination Decision

Our Embryogenesis Success Rate
On average, the brassica plant is supposed to
produce 89 seeds per plant. Here are our actual
results.
Lisa produced 14 seeds from her class, and her
mutant plants produced 80 seeds.
Brant produced 12 seeds for mutant, and 51 seeds for
his class brassica
Scot produced 51 seeds for his class brassica, and 49
seeds for his mutants
Janet produced 0 seeds for her class brassica, and 16
seeds for her mutants
The Experimental Method We Used
to Test Our Offspring
The method that we used to test
our offspring was putting them
in seed germination plates with
wet paper towels to enhance
their growth rates.

Our Conclusion
We conclude that this project was very
informative and we learned a lot from it. We
learned about plant’s genotypes and how
genetic traits influence a plant’s physical
characteristics. We hope that we helped the
scientists with their research about plants in
dry climates. As soon as our seeds grow in our
seed germination plates, we will see if our
research question was relevant.
