<h2>The approimate sizes of the DNA fragments for Mother </h2>
800 bp and 260 bp are the approximate sizes of the DNA fragments for the mother. The appearance or inadequacy of specific identifying places in a DNA specimen produces changeable dimensions of DNA fragments, which are isolated utilizing gel electrophoresis. They are then hybridized with DNA scrutinies that join to a corresponding DNA series in the example.
