Apolygenic trait is contributed by two or more genes one gene two alleles multiple alleles

The correct answer would be two or more genes.

Explanation:

Polygenic traits are characters whose phenotypes are influenced by two or more genes. These traits are displayed in continuous distribution. These characters generally have two alleles of each gene but can have multiple alleles too.

Height is also a polygenic trait in humans. Humans can be of different sizes. It is controlled by three genes and six alleles. Eye color, skin color and other traits also polygenic traits in humans.

Thus, the correct answer would be two or more genes.

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.
