NEET BIOLOGY

Detailed explanation-1: -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-2: -Key Points. Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population. Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).

Detailed explanation-3: -Answer and Explanation: The given statement is True. The evolution does not stop in an organism, and it continues to evolve throughout its lifetime. Every population of species undergoes some sort of evolution, and it varies from one species to another.

Detailed explanation-4: -Individuals do not evolve; populations evolve. ›Evolution is measured as changes in relative proportions of heritable variations in a population over several generations. Natural selection can only work on heritable traits. Acquired traits are not heritable and are not subject to natural selection.
