You are a xenogeneticist studying groggins from the planet zabar. they do not have males and females, but there are mating types: alpha and omega. groggins are hard to grow in the lab, so you are using several families of parents and offspring to determine the genetic basis of the tail spine color trait. spines may be black, red or yellow. use the data from the families below (parental gentoypes are unknown) to answer questions 1 - 3. parents offspring family alpha omega alpha omega 1 black red black black 2 yellow yellow yellow ½ yellow ½ red 3 black yellow black black 4 red yellow yellow red 5 black yellow ½ black ½ black ½ yellow ½ yellow 6 black red ½ black ½ black ½ yellow ½ yellow 7 red black black red 1. the genotype of the red parent in family 6 is best described as: a. r/r b. r/r c. r/y d)x /x e. x /

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.

True but only in the south coastal areas during september and early october.
