In order to determine the inherited colors in the flowers we started out by crossing green-1 and a white flowers.
Objectives
- Produce a true-breeding purple flower by using the Aipotu program.
- Determine what alleles are dominant or recessive.
Observations
- When crossing a pure breeding green flower with a pure breeding white flower all of the offspring produced were green. Green is the dominent allele and in this first test-cross the white flowers are the recessive allele.
- When I self crossed flower 1-12 from my first cross, 3 white flowers appeared in 2-1, 2-10,and 2-20; this shows that the green flower I chose was a heterozygous flower.
- Ran 2 mutation trials with 2-10 and 2-20 and the results were all white offspring with both. After mutating 2-1 there was a difference, 2-1 produced a single red flower.
- Self-crossed the red flower (6-6) that resulted from mutating the white flower in 2-1 and the result was that the dominant flower was the red one in this case, however some whites were produced.
- Mutated the red mutated flower (6-6) and the result ended up with many red flowers, 2 white flowers, and one orange flower(8-5).
- After self crossing the orange flower, it produced yellow, orange, and white flowers.
- I added the first orange flower to my greenhouse.
- Crossed orange mutant with green 2 and produced a new purple flower.
- crossed green 2 and purple from above and produced blue, orange, green, and purple flowers.
- crossed blue and purple from greenhouse and produced ONLY blue and purple offspring.
- crossing purple and red creates purple, red, and blue offspring.
- Blue is the dominant flower when self-crossed.
- green-1 only produces green when crossed with anything.
- green-2 self cross produces green, yellow, and blue flowers; this shows incomplete dominance.
