DNA fingerprinting is a laboratory technique used to establish a link between biological evidence and a suspect in a criminal investigation. A DNA sample taken from a crime scene is compared with a DNA sample from a suspect. Most recently, DNA fingerprinting has been expanded into fields other than forensics including agriculture as well as animal breeding programs. Fish hatcheries in the mountain states are hoping to begin a breeding program that combines the best features of two fish varieties to create a super fish; one that could withstand the extremes in water temperatures as well as water pH. Scientists want to find a fish that they can breed with brown trout, a hardy fish that can withstand many adverse environmental conditions. Based on the DNA profiles of the four trout varieties, which fish would be the best choice for the breeding program? A) Brook trout Eliminate B) Golden trout C) Rainbow trout D) None of the three as they are different species.

Answer is option "C"

Explanation:

The rainbow trout is local just to the streams and pools of North America, west of the Rocky Mountains, yet its incentive as a hard-battling game fish and scrumptious dinner has represent its presentation all through the worldRainbow trout, also called redband trout, are lovely fish, with shading and examples that differ generally relying upon environment, age, and generating condition. They are torpedo-formed and by and large blue-green or yellow-green in shading with a pink streak along their sides, white underbelly, and little dark spots on their back and bladesHence, the right answer is option C "Rainbow trout"

Mantle convection  is the slow  creepingmotion of earth's solid silicate  mantle  caused by  convection  currents carrying  heat from the interior  to the planet's surface.[1][2]  the earth's surface  lithosphere, which rides atop the  asthenosphere  (the two components of the  upper mantle), is divided into a number of  plates  that are continuously being created and consumed at their opposite  plate boundaries. accretion occurs as mantle is added to the growing edges of a plate, associated with  seafloor spreading. this hot added material cools down by  conduction  and  convection  of heat. at the consumption edges of the plate, the material has thermally contracted to become dense, and it sinks under its own weight in the process of  subduction  usually at an  ocean trench.[3]this subducted material sinks through the earth's interior. some subducted material appears to reach the lower mantle,[4]  while in other regions, this material is impeded from sinking further, possibly due to a phase transition from  spinel  to  silicate perovskiteand  magnesiowustite, an  endothermic reaction.[5]the subducted oceanic crust triggers  volcanism, although the basic mechanisms are varied. volcanism may occur due to processes that add buoyancy to partially melted mantle causing an upward flow due to a decrease in density of the partial melt.secondary forms of convection that may result in surface volcanism are postulated to occur as a consequence of intraplate extension[6]  and  mantle plumes.[7]it is because the mantle can convect that the  tectonic plates  are able to move around the earth's surface.[8]mantle convection seems to have been much more active during the  hadean  period, resulting in gravitational sorting of heavier molten  iron, and  nickel  elements and  sulphides  in the core, and lighter  silicate minerals  in the  mantle.
