Ralph's selective breeding process likely increased the likelihood of offspring inheriting the purple flower trait. Through six generations of breeding only purple-flower producing plants, he would have amplified the presence of the desired trait in the gene pool. This process demonstrates how selective breeding can influence the genetic makeup of a population over time to favor specific traits.
Selective Breeding
as it is a selective media for streptococci it inhibits the growth of other bacteria.
Selective pressures can impact genetic variation by favoring certain traits or alleles while reducing the frequency of others in a population. Strong selective pressures can lead to genetic changes over generations as individuals with advantageous traits are more likely to survive and reproduce. Conversely, weak or fluctuating selective pressures may allow for higher genetic variation to persist within a population.
In artificial selection, humans act as the selective agent by choosing which individuals will breed based on specific traits desired for future generations. Through this process, humans influence the genetic makeup of the population over time to enhance particular characteristics.

The advantages of selective breeding include producing a dog that meets the standard of the breed. Disadvantages include producing dogs with very short faces, squat legs, and large bodies.

It can be very effective, depending on how aggressive you are with your breeding program, and how well you keep your records.
If gold bearing mass is rich enough, grinding and panning. If not rich enough, grinding, selective dissolution for gold and precipitation
evolution - apes continued to evolve as well. We came from all mamals, reptiles etc... each species continued to evolve into its own lines. All dogs came from the selective breeding from wolves, and wolves continue to exist.
Upon generations and generations and generations of selective breeding, dairy cows have been selected to not only give more milk than their calves can take in, but also to be docile and easy to handle in the milking parlor. Genetics, my friend, is the reason why dairy cows have less of a flight zone. It is not a good thing when dealing with dairy bulls though.
