Mortality is a data piece for a demographer that would be interested in studying demography. It is fundamental to estimate population size.
<h3>What is mortality in demography?</h3>
Mortality refers to the rate of deads in a given population for a particular period of time (often one year calendar).
Conversely, the birth rate refers to the rate of births in a given population for a particular period of time.
Demography is a discipline that studies human population dynamics, which includes both mortality and birth rates.

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.
