What is the advantage of using STR for the identification of bodies from a mass disaster, such as the World Trade Center?
never [62]
The correct answer is C. Short tandem repeats are mostly different in unrelated peoples' DNA. Therefore, it is used to match the DNA of the people of the related family for identification of bodies, during a mass disaster like World Trade Centre. DNA from the nucleus is extracted in the process, and the STR containing regions are amplified and studied and can be matched with that of the relatives.

koban [17]

Answer:

<h2>Genotype is the set of genes( allele) of an organism. </h2><h2>Phenotype is the physical expression of the genetic composition of an organism. </h2>

Phenotype: 1. Physical expression of the genetic composition of an organism resulted as  phenotype.

2. It  is the physical expression of genes (alleles) which are responsible for any trait.
