There are total five steps in DNA fingerprinting, which include isolation of DNA from the cells, digestion of DNA with restriction enzymes, separation of DNA fragments in agarose gel, transfer of DNA fragments to a blotting paper, and labeling of DNA fragments with radioactive probes of specific sequence to see the results.

Explanation:

The genotype of an individual represents the total number and types of genes and the alleles of each gene present in the nuclei of its cells. In humans, the presence of two copies of X chromosomes makes an individual female. However, some individuals have two copies of X chromosomes but have masculine features. Similarly, some individuals have one X and one Y chromosomes in their cells. These individuals are genotypically males. But they have some feminine features. This makes them phenotypically female. Phenotype is the morphological expression of genotype.
