Two true-breeding white strains of the plant illegitimati noncarborundum were meted, and the fl progeny were ell white. when the fl plants were allowed to self-fertilize, 126 white-flowered end 33 purple- flowered f2 plants grew. how could you describe inheritance of flower color? a. describe how specific alleles influence each other end therefore effect phenotype b. a white f2 plant is allowed to self-fertilize of the progeny, 3/4 are white-flowered, end 1/4 ere purple-flowered. what is the genotype of the white f2 plant? c. a purple f2 plant is allowed to self-fertilize. of the progeny, 3/4 are purple-flowered, and 1/4 are white-flowered. what is the genotype of the purple f2 plant? d. two white f2 plants are crossed with each other. of the progeny, 1/2 ere purple-flowered, end 1/2 are white-flowered. what are the genotypes of the two white f2 plants?

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.

D. the maximum number of species that can live in an ecosystem.
