Chromosome #2 with locus TPOX with a length of 248 base pairs was only found in the parent sample A. None of the chromosomes from sample b matched the chromosomes from A, C, or D+E except for maternal TPOX chromosome from B and the paternal TPOX from C. 3. Would this exercise still work properly if you had chosen any combination of maternal and paternal chromosomes for chromosomes 2, 5, 7, and 13 from samples D & E? Yes because the maternal and parental chromosomes would still be put on the electrophoresis table. The parents turn out different based on DNA combos that are chosen. 4. What is the term for the random arrangement of homologous pairs of chromosomes during the first division of meiosis? Independent Assortment 5. What role does the Polymerase Chain Reaction (PCR) play in producing a DNA Profile? PCR amplifies the regions of DNA with short tandem repeats and uses primers with fluorescent labels. This works by replicating the region of DNA several times. The same region is also amplified on both chromosomes, however they are different sizes, which are then put into gel
