Telophase 2 is the final step of meiosis 2 in which homologous chromosomes reach the opposite poles and four haploid cells are formed.
Explanation:
The telophase 2 ends up in four haploid (n=2) cells. It is in this phase the genetic material of the parent cell is divided into 2 daughter cells. The events taking place are nuclear membrane reappears (karyokinesis has taken place by now), spindle fibres and astral rays disappear, chromosomes decondensed to become chromatids (thin fibres), constriction on equatorial plate consequently four daughter cells formed.
Answer:
The mitochondrial DNA (mtDNA) is passed down from the mother to the children almost unchanged. The analysis of mtDNA has provided the forensic scientist with essential tools for determining the source of DNA that they have recovered even from small biological samples. Thus, the answer to the question above is letter B.
