The statement 'a suspect’s mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene' is TRUE about mtDNA.
<h3>What is mitochondrial DNA?</h3>
Mitochondrial DNA (mtDNA) is a special class of genetic material contained inside the mitochondria of eukaryotic organisms.
This genetic material (mtDNA) may result very useful to identify samples by making comparisons of the nucleotide sequence.
Mitochondrial DNA typing is a useful strategy used in criminology based on matching an unidentified sample of mtDNA with another obtained at the crime scene.
In conclusion, the statement 'a suspect’s mtDNA sample is matched to an unknown sample of mtDNA that was found at a crime scene' is TRUE about mtDNA.

Ovulation and ejaculation are the processes that involve the release of the female and male gamete for the process of fertilization.
<u>Ovulation</u>
- The release of an egg from one of a woman's ovaries is known as ovulation.
- Ovulation usually lasts for one day and takes place two weeks before a woman anticipates getting her period, in the midst of her menstrual cycle.
- However, the procedure takes a different amount of time for every woman, and it might even change from month to month.
- A sperm cell can fertilize an egg when it exits a woman's ovary and enters the fallopian tube.
- Sperm can survive for three to five days inside a woman's reproductive system.
- The uterine walls thicken during ovulation in order to accommodate a fertilized egg. On the other hand, if the egg is not fertilized, the uterine lining is lost around two weeks later, which results in menstruation.
<u>Ejaculation</u>
- Ejaculation, the male reproductive system's discharge of sperm cells and seminal plasma.
- Sperm are transported from the testicles and the epididymis, where they are stored, to the beginning of the urethra, a hollow tube that runs through the pen!s and transports either sperm or urine.
- In the second stage, known as the actual ejaculation, the semen is transported through the urethra and expelled from the body.
