. You have discovered a rare, fresh water squid, W. hamiltonae, living in Lake Monroe. Further investigation reveals two true-breeding strains, one with blue spots and short tentacles, and one with yellow spots and long tentacles. In crosses between the two strains, the F1 offspring always exhibit long tentacles and yellow spots. When you cross the F1's, you found 179 with long tentacles and yellow spots, 58 with long tentacles and blue spots, 63 with short tentacles and yellow spots and 20 with short tentacles and blue spots. What are the genotypes of the two original strains

The tasmanian devil, a marsupial carnivore, is facing extinction due to devil facial tumor disease (dftd) which causes bulging cancerous lumps and lesions to erupt around the face and neck — often causing enough deformation to make seeing or eating difficult. dftd has evolved into a contagious cancer, a trait that is unique among cancers. devil mating behavior involves biting around the head and neck, allowing cells from one individual — especially cells from the crumbly dftd tumors — to be transferred to the wounds or face of a new individual. this marsupial was once found across australia, but sea levels rose, isolating the tasmanian population, while the australian population went extinct. what would be an outcome of genetic isolation that is likely to have impacted the spread of dftd? a) reduced territory puts diseased individuals in greater contact with non-diseased ones. b) inbreeding results in less variation in facial features so the cancer is generally fatal. c) genetic isolation has made it difficult for scientists to develop a vaccine against dftd. d) the lack of genetic variation in the immune system of tasmanian devils minimizes resistance to the disease.
