With chromosomes crossing over frequently, it's more likely that genetic defects will occur in offsprinfg.
The correct answer is: The recessive allele produces a phenotype that is better able to survive and reproduce than the dominant phenotype.
Natural selection (adaptation mechanism), gene flow, and mutation combine to change allele frequencies across generations. Natural selection tends to increase in frequency beneficial alleles, while it tends to decrease in frequency deleterious alleles.
