The characteristics resulting from the gene are advantagous for the survival of the population, or at least more so than its alternative(s) in the conditions of the time period through which it presides.

Genes are the hereditary molecules that natural selection actually selects, So, the change in allele ( different molecular form of the same gene ) frequency over time in a population of organisms is the definition of evolution.
Gene shuffling is when the natural trait of a single phenotype favours over the extreme traits over the intermediate.
Evolution is the change in allele ( different molecular form of the same gene ) frequency over time in a population of organisms.

Simply, evolution.
Simply, evolution.
Recessive genes are replaced by dominant genes over time and unfavorable genes die out.
A change in the genetic composition of a population of organisms over time is known as evolution. This occurs through processes such as natural selection, genetic drift, and gene flow, leading to changes in allele frequencies in a population's gene pool. These changes can result in the emergence of new traits, species, and adaptations.
Not sure what you are asking, but, evolution is the change in allele frequency over time in a population of organisms.
There is no gene flow - APEX
The gene that expresses itself over the other is Dominant. The former gene is recessive.
