The nervous system
Enviroment, development, and behavior are all factors besides alleles that can affect phenotypes.
Physical characteristics of organisms are called phenotypes. These traits are the observable characteristics of an organism, such as its color, size, shape, and behavior. Phenotypes are the result of an organism's genetic makeup interacting with its environment.
It doesn't. Phenotypes are viable or not in a given environment, and this influences whether the corresponding genotypes get passed on. Selection works on genotypes via the effects of their expression, their phenotype. The answer you may be looking for is that phenotypes maladapted to their environment have less babies, and pass on less copies of their genes. "Natural selection" is the whole process over generations. "Selection" may refer to misadapted bodies/phenotypes reproducing less due to illness, hunger, bad quality territories, dying earlier, etc.
Stabilizing selection would result in a graph showing a peak at the intermediate phenotype, with fewer individuals at the extreme phenotypes. This is because individuals with intermediate phenotypes are favored, leading to the reduction of extreme phenotypes in the population over time.
Non-examples of phenotypes would include things like DNA sequences, genotypes, or gene variants. Phenotypes are the observable characteristics of an organism resulting from the interaction of its genotype with the environment. They are not the underlying genetic information itself.
Genotypes are not created by phenotypes, they are the alleles/genes of the organism. Genotypes (in combination with environment) produce phenotypes. It would be expected that the genotypes Bb and BB would produce the phenotype B.
How do faults affect the environment
The phenotypes present in the F1 generation depend on the phenotypes of the parental generation (and the environment). The F1 generation will display the dominant trait(s). For example, if T is tall and t is short, in the cross TT X tt the F1 generation will have the phenotype corresponding to the T allele (tall).
Aa AA aa If A dominant, two phenotypes.

Meteorology does not affect the environment in any way
believe it or not hydroelectric dams do affect the environment.
