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

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
