A dominant trait will mask a recessive trait.
Yes, it is true that evolution is a theory, which is a well substantiated explanation for observable facts.
Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction.
Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.
Evolution occurs when evolutionary processes such as natural selection (including sexual selection) and genetic drift act on this variation, resulting in certain characteristics becoming more common or rare within a population.
The evolutionary pressures that determine whether a characteristic would be common or rare within a population constantly change, resulting in a change in heritable characteristics arising over successive generations. It is this process of evolution that has given rise to biodiversity at every level of biological organisation, including the levels of species, individual organisms and molecules.

Answer:
FOX promotes the expression of the gene HOUND indirectly.
Explanation:
It is likely that there is another protein (protein X) that is involved. For example FOX maybe increasing the expression of protein X which may activate the expression of the HOUND gene through cell signalling or protein-protein interactions.
They saw how their are different variations of animals and how not all humans are alike with different genetic traits and physial apprerance
The answer top the question given above is letter c. Surface currents.
There are two types of ocean currents, surface current and deep currents.
Surface currents which are caused by winds,move warm water
away from the equator and cool water away from the poles. Deep currents on the other hand are driven by differences in water density.
