NEET BIOLOGY

Detailed explanation-1: -Answer:Natural selection results in change over time by acting on traits that are advantageous traits. Explanation: Advantageous traits: Traits that give them an advantage within their environment; these individuals will survive to reproduce and pass on those traits to their offspring.

Detailed explanation-2: -Populations Evolve Natural selection can only work on heritable traits. Acquired traits are not heritable and are not subject to natural selection. Environmental factors are variable. A trait that is beneficial in one place or time may be detrimental in another place or time.

Detailed explanation-3: -Natural selection is a non-random difference in reproductive output among replicating entities, often due indirectly to differences in survival in a particular environment, leading to an increase in the proportion of beneficial, heritable characteristics within a population from one generation to the next.

Detailed explanation-4: -In natural selection, genetic mutations that are beneficial to an individual’s survival are passed on through reproduction. This results in a new generation of organisms that are more likely to survive to reproduce.

Detailed explanation-5: -Evolution: Evolution consists of changes in the heritable traits of a population of organisms as successive generations replace one another. It is populations of organisms that evolve, not individual organisms.
