No. Typically the symptoms of HD do not become apparent until long after a person would be of child bearing age.
Yes, natural selection plays a role in the evolution of genetic resistance to malaria. Individuals with genetic traits that provide resistance to the disease are more likely to survive and pass on their genes, leading to a higher prevalence of resistance in populations where malaria is endemic. This evolutionary process is an example of natural selection in action.
The different methods of plant breeding for disease resistance includes seed selection, pedigree selection,recurrent selection,use of natural or artificial induced mutants etc.
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
It hasn't. Natural selection is a key part of the ecosystem itself.
Directional selection
Genetic variation is important for natural selection to drive evolution because it provides the raw material for natural selection to act upon. Without genetic variation, there would be no diversity in traits for natural selection to favor or eliminate, and evolution would not be possible.
No, there should not be a cure to every disease. Natural selection is a basic function of life, and often disease is part of that natural selection. Imagine the population explosion of humans if we could cure all disease? If we weren't dying from disease, then we'd be dying from famine.
No genetic variation in the cheetah population gene pool, so natural selection has nothing to select from and the inbreeding depression keeps deleterious traits breeding true among cheetahs and natural selection can not eliminate them from the gene pool.
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.

Adaptation does not allow for natural selection: natural selection causes adaptation.

The prefix of natural selection is "natural" and the suffix is "-tion".
Most crohns disease sufferers benefit from a diet of fresh vegetables, fruits, natural grains and proteins. Try to eliminate processed foods and foods with additives and preservatives.
Genetic variation in itself does not 'support' natural selection: it is what natural selection acts upon.
