Inbreeding depression is a serious concern in small populations of endangered organisms. why is inbreeding depression a concern for such populations?

Inbreeding results in small genetic diversity in the offsprings as parents are mating within the same 'family tree', which is often the case for endangered organisms. With little genetic diversity, there is no variation for natural selection to act on and hence the species is vulnerable to changes in their environment. Any change in the environment has the potential to wipe out the entire population as there is no genetic diversity that allows a selected few to withstand the environmental change. For example, if there were to be a temperature change in the habitat, the endangered species could go extinct.

Explanation:

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
