Hybrid vigor

Explanation:

One of the desirable results of breeding individuals of different parentage is hybrid vigor, otherwise known as heterosis or inbreeding enhancement. It is simply the desirable quantitative, physiological and or biological improvements that manifest in hybrids. By definition, hybrids refer to progenies of genetically different parents.

Hybrid vigor is in direct contrast with inbreeding depression - the enhancement of potentially fatal traits that usually occur in progenies of inbreeding. Inbreeding in itself is the mating between genetically close individuals.

There are two hypotheses that have been formulated to support the fact that hybrids exhibit improved traits compared to their parents;

Hence, the correct answer is hybrid vigor

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.
