Will a disease-causing gene be removed from the population through natural selection if it has no negative effect on its carrier?
Natural selection is the process by which organisms with traits that make them better adapted to their environment are more likely to survive and reproduce. These traits are then passed on to their offspring, and over time, the population becomes more adapted to its environment.
If a disease-causing gene has no negative effect on its carrier, it will not be removed from the population through natural selection. This is because natural selection only removes genes that are harmful to the organism. In the case of a disease-causing gene that has no negative effect on its carrier, the gene will not be removed from the population because it does not provide any disadvantage to the organism.
However, if the disease-causing gene is linked to another gene that does have a negative effect on its carrier, then the disease-causing gene may be removed from the population through natural selection. This is because the negative effect of the linked gene will make it less likely for the organism to survive and reproduce, and the disease-causing gene will be passed on less frequently to the next generation.
