Two sister chromatids are held together by the centromere
<h3>The Chromosome</h3>
The chromosome consists of 2 sister chromatids that are linked together by a structure known as the centromere.
Each of the sister chromatids carries an allele of the same gene.
The link between the two sister chromatids is broken at the anaphase stage of the cell division when spindle fibers pull them apart towards opposite poles within the cell.

evolutionary sense fitness refers to the measure of reproductive success of an
individual or of organisms in general. Those organisms that leave the largest

fecundity selection. Fitness is critical for a species’ survival and is a major
adaptation that all organisms do through a long period of time. <span> </span></span>
