Directional selection
I do not know if I would say " catagorically good ", but stabilizing selection does eliminate the extreme morphologies in a population of organisms. Remember the taget of selection is the individual ( gene ) and the population evolves. So, saying something that is the result of natural selection is " good " for the population is rather confused as individuals are selected. So, extreme morphologies could be " good " for a population depending on the immediate environment.
Natural selection is a term that, if you stated it fully, would say something like "The fittest individuals are naturally selected for reproduction." Unfit organisms do not survive to reproduce and pass on their genes.
No. Typically the symptoms of HD do not become apparent until long after a person would be of child bearing age.
This is caused by natural selection, and it would increase the frequency of the white alleles.
What population? Perhaps you mean if there were no variation for natural selection to select from.
Yes, that would be called the Homologous structure, and that changes in natural selection.
Yes it does. Without variance in the organisms genome, that gives variance to the phenotype, there would be nothing for natural selection to select from.
it would die
False, dog breeding would be an example of Artificial Selection.
In Darwin's time, it would be classified as "natural" selection.
False, dog breeding would be an example of Artificial Selection.
That would be disruptive selection.
