Answer from: aoexus

Essentially traits of both genes will be shown. Take heterochromia for example, where a person has a green eye and a blue eye, both have some part in developing a trait.

I answered a similar question before so I'm going to use an example from there. Two plants, a dark purple flower and a white flower create an offspring with dark purple and white petals on the flower. This is an example of the gene displaying codominance in effect.

Codominance allows for two genes to exist independently at the same time without mixing. Think of another example. Say your mother has blue hair and your dad has red hair. If you have both blue and red strands. That is codominance. The two colors who co-exist. If you got purple, you would have incomplete dominance. Notice that the purple is a mix and of blue and red. They are dependent on each other.

Hope that helps! :D

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.
