In wisconsin, a very large population of lake trout, in which individuals mate at random, experiences no migration, mutations, nor selective pressure for a number of years. which of these is most likely to occur in the population? the answers to choose from >
~the frequency of dominant alleles will slowly increase.
~the gene pool of the population will remain relatively constant.
~the genetic variability of the population will slowly decrease.
~the frequency of dominant and recessive alleles will equalize.

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
