In the genetic mapping exercise we have talked about this semester, mutant virgin female flies were mated with wild type male flies and the phenotype of the F1 offspring from this first cross were scored and used to set up a second cross on March 1. When the first F2 progeny begin to emerge, they seem to be mostly wild type flies. Explain why we might see this and how these results might affect the genetic map we are creating from the F2 data.

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
