ANSWER) Allelic ladder
EXPLANATION
Short tandem repeats (STR) is a tandem repeats of 1-6 basepair and is about 100 nucleotide long. It is also known microsatellite as well as simple sequence repeat (SSR). Allelic ladder consist of alleles which are known and are obtained through PCR(polymerase chain reaction). The alleles are of different loci and represent the Variation of STR marker that are present in the ladder.
Exclusion of other option
See the mutation and somatic mutations are the random change in nucleotide sequence which include insertion, deletion and substitution. The later one is mutation present in somatic cell. It is a major factor associated with genome profiling of an individual.
Chromosome: it is Highly condensed and compact structure of DNA present within cell nucleus.
