NEET BIOLOGY

Detailed explanation-1: -Through this process of natural selection, favorable traits are transmitted through generations. Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

Detailed explanation-2: -If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection).

Detailed explanation-3: -In order for natural selection to operate on a trait, the trait must possess heritable variation and must confer an advantage in the competition for resources. If one of these requirements does not occur, then the trait does not experience natural selection.

Detailed explanation-4: -Offspring are a random genetic recombination of all of the traits, good and bad, from both of their parents. The advantageous traits eventually become more prevalent in nature because those offspring who randomly inherited the advantageous trait are more successful in surviving and producing offspring of their own.

Detailed explanation-5: -For a trait to undergo positive selection, it must have two characteristics. First, the trait must be beneficial; in other words, it must increase the organism’s probability of surviving and reproducing. Second, the trait must be heritable so that it can be passed to an organism’s offspring.
