Previously, it was thought that the blending hypothesis explained inheritance. the blending hypothesis maintained that
a. the characters governed by genes in the egg are different from the characters governed by genes in the sperm
b. many genes are lost in their transmission to offspring, but the remaining genes gradually reproduce the lost genes
c. mutation is the major source of new gene combinations
d. after a mating, genes of the two parents are mixed in the offspring and lose their individual identities

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
