Homologous chromosomes have the same genes on the same loci. However, they may have different forms of the same gene called alleles. These sister chromosomes, of a homologous pair, separate during anaphase I of meiosis. The two daughter cells formed will, therefore, have half the genetic material as the parent cell. This is because they will only have one set of the genes (as in diploid organisms) and are called gametes.
Subsets of {dog, cat, fish} are Ф, {dog}, {cat}, {fish}, {dog, cat}, {dog, fish}, {cat, fish}, {dog, cat, fish}.
Water in the ocean move differently depending of the win speed. In the ground, it only moves downward due to gravity pulling in the water while the soil absorbs the water. Water above ground only go one direction due to the slope of the mountain or riven.
I would assume a population with greater diversity would survive above quantity because of the varying difference in the genetic capabilities.
