Start with the p generation with the following genotypes (aa x aa). based on classical mendelian inheritance, how will a cross between two homozygous parents, one dominant and one recessive, influence future generations?

a) the f1 generation will show an even split between the dominant phenotype and the recessive phenotype.

b) the f1 generation will all show the dominant trait and future crosses will continue to produce genotypes expressing the dominant trait.

c) although the f1 generation will all show the dominant trait, the offspring will all be heterozygous and increase chances of future variation.

d) the f1 generation will show a mix of the dominant phenotype and recessive phenotype and over generations the recessive trait will increase in number.

c. earths continental crust is thicker than its lithosphere.

because, the lithosphere is the outermost layer of the earth/ 100 km thick and is defined by its machanical properties.the lithosphere contains oceanic and continental crust that varies in age and thickness across locations and geologic time. the lithosphere is the coolest layer of the earth in terms of temperature. the term lithosphere should not be confused with the use of "geosphere" which is used to indicate all of earth systems, including the atmosphere, hydrosphere   and biosphere. the surface of the earth can be divided into the continental crust and the oceanic crust.   the continental crust is made mostly of granite while the oceanic crust is made of basalt. the average thickness of the continental crust is 25 miles and the average thickness of the oceanic crust is 5 miles.   three types of rock, igneous, sedimentary, and metamorphic, make up the surface of the earth. that's why 3 option is preferable.
