A cross was made between a plant that has blue flowers and purple seed to a plant with white flowers and green seed. The following data were obtained: F1 dihybrid: All offspring had blue flowers and purple seeds F2 Testcross: 103 blue flowers, purple seeds 49 blue flowers, green seeds 44 white flowers, purple seeds 104 white flowers, green seeds 300 Total a) Based on the F1 phenotype, which allele for each of the two genes is dominant, and which is recessive

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.
