The correct option is A.
Fitness refers to the quantitative representation of natural and sexual selection within an evolution. Fitness can be defined in respect to a genotype or a phenotype. Relative fitness is described as the survival or reproductive rate of a genotype or phenotype relative to maximum survival or reproductive rate of other genotypes in the population. Thus, the fitness of a population can be determined by finding out the number of offspring that survive to adulthood.

Answer:

Human genome has various replicons.

Explanation:

A replicon which is a unit of DNA, has potential to get replicated independently. So, the DNA replication occurs simultaneously at various replicons as a result of which human genome takes much less time than estimated to get replicated .

In contrast to this, prokaryotes like E.coli have only one origin of replication and thus one replicon due to which replication is restricted to once per cell cycle.
