Natural selection is when favorable traits are passed down to offspring while harmful and less favorable traits are eliminated, due to higher predation, competition from the o â¦ rganisms with more favored traits, etc. Since organisms with more favored traits will, logically, have much more chance of surviving to reproduce than those who lack the favored traits, the next generations will slowly start to accumulate a higher percentage of organisms who have the favored traits.
Describe how adaptive traits increase the fitness of individuals in a particular environment. Adaptive traits increase in frequency because they enhance individual survival and reproduction of individuals in a population. Biological fitness is measured by the proportion of genes compared with all the genes in population. Traits are often a trade-off between survival and reproduction, so that natural selection optimizes the evolution of traits that allow survival while maximizing reproductive success.
