Genetics of Body color and body shape
By: Justin & Britney
HYPOTHESIS: The brown body and the long body are the dominant traits for a dragonfly.
EXPERIMENT:
Brown/Long and Brown/Pointy dragonflies were crossed (see Cage 2)
Brown/Long and Gray/Long were crossed. (See Cage 3)
Brown/Long and Gray Long were crossed again. (See Cage 4)Brown/Long and Gray/Long were crossed again. (See Cage 5)
CONCLUSION: Our hypothesis was falsified. The dominant traits for a dragonfly are a gray body and a pointy body. We inferred this by finding the cross between a brown/long and brown/pointy to give only pointy offspring; therefore, pointy is dominant (See Cage 2). After 3 crosses between brown/long and gray/long, the last cross gave offspring with only gray/long bodies; therefore, gray is the dominant color. (See cage 5)
