GENERAL KNOWLEDGE

Detailed explanation-1: -Darwinian fitness of an organism is focused on it’s reproductive fitness. It stated that any species having better adaptibility will leave progenies through reproduction and thus will ensure continuity on earth more than less adaptive ones. Reproductively fit individuals survive and are selected by nature.

Detailed explanation-2: -natural selection quantified by a measure called Darwinian fitness or relative fitness. Fitness in this sense is the relative probability that a hereditary characteristic will be reproduced; that is, the degree of fitness is a measure of the reproductive efficiency of the characteristic.

Detailed explanation-3: -Abstract. Life-history traits or “fitness components"-such as age and size at maturity, fecundity and fertility, age-specific rates of survival, and life span-are the major phenotypic determinants of Darwinian fitness.
