The garden flower Salpiglossis sinuata (painted tongue) comes in many different colors. Several crosses are made between true-breeding parental strains to produce F1 plants, which are in turn self-fertilized to produce F2 progeny. Parents F1 phenotypes F2 phenotypes red × blue all red 102 red, 33 blue
lavender × blue all lavender 149 lavender, 51 blue
lavender × red all bronze 84 bronze, 43 red, 41 lavender
red × yellow all red 133 red, 58 yellow, 43 blue
yellow × blue all lavender 183 lavender, 81 yellow, 59 blue
a. State a hypothesis explaining the inheritance of flower color in painted tongues.
b. Assign genotypes to the parents, F1 progeny, and F2 progeny for all five crosses.
c. In a cross between true-breeding yellow and truebreeding lavender plants, all of the F1 progeny are bronze. If you used these F1 plants to produce an F2 generation, what phenotypes in what ratios would you expect? Are there any genotypes that might produce a phenotype that you cannot predict from earlier experiments, and if so, how might this alter the phenotypic ratios among the F2 progeny?

Hunting in the darksome fish rely on senses beyond sight. in the darkness of the marianas trench, a fish called the rattail has an extremely sensitive sense of smell. the fish uses scent, rather than sight, to steer toward food. once it's near food, the rattail uses a special organ on the bottom of its chin to guide itself by feel.marine snowone staple of the deep sea diet is "marine snow," flakes of organic, edible substances that sink down from the upper ocean. animals at the ocean's bottom find sustenance in everything from the bodies of dead creatures to fecal matter. marine snow is diverse enough to support numerous species. for instance, several species of snails and worms feed exclusively on deceased whales.microorganismsthe deep sea is an intricate ecosystem, and even the ocean floor itself plays a part. hydrothermal vents are cracks in the sea floor where erupting magma mixes with ocean water to produce plumes of hot, sulfur-rich chemicals. some microbes can use these chemicals for energy, sustaining their existence and that of the animals who depend on their roles in the deep sea food chain.
