A cross was made between a plant that has blue flowers and purple seeds and a plant
Question:
A cross was made between a plant that has blue flowers and purple seeds and a plant with white flowers and green seeds. The F1 generation was then allowed to self-fertilize. The following data were obtained:
F1 generation: All offspring have blue flowers with purple seeds.
F2 generation: 208 offspring with blue flowers, purple seeds; 13 with blue flowers, green seeds; 19 with white flowers, purple seeds;and 60 with white flowers, green seeds. Total = 300 offspring.Start with the hypothesis that blue flowers and purple seeds are dominant traits and that the two genes assort independently. Calculate a chi square value. What does this value mean with regard to your hypothesis?If you decide to reject the hypothesis, which aspect of the hypothesis do you think is incorrect (i.e., that blue flowers and purple seeds are dominant traits, or that the two genes assort independently)?
