Crosses to determine the origin of the body color of orange GloFish. (A) Punnett square describing the first test cross and images of parental and progeny phenotypes. If the hypothesis was correct, the students expected all of the progeny to have an orange body color, which exactly matched the results of this test cross. (B) Punnett square describing complementary test cross and images of parents and selected progeny. If the hypothesis is correct, the cross should produce red and yellow progeny. Consistent with the hypotheses and the predictions from the Punnett square, yellow (n=5), red (n=2), orange (n=5), and gray (n=1) progeny were produced. All images are lateral views with anterior to the left. |
