Because most human characteristics are complex, many genes act together to determine a trait. this is called:

The correct answer is - Polygenic inheritance.

Explanation:

Polymeric inheritance takes place if a trait is influenced by two or more genes at a time. The genes can be normally high in numbers but show minute influences in the particular trait.

In humans, there are many complex gene interactions that control different characters of traits such as hair color, eye color, the height of individuals, and weight or skin color. There are many more traits that show polygenic inheritance.

Thus, the correct answer is - polygenic inheritance.

answer; /// i believe that the correct answer is; ///a combination of the birth and death

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
