Sites within the human genome where a short nucleotide sequence is repeated many times in a row are known as short tandem repeats.
DNA sequences with 2 to 6 base pairs are known as short tandem repeats (STRs), and they are dispersed throughout the genome. Multiple repetitions of these brief sequences are possible, and the number of repetitions varies greatly between people. The capacity to distinguish one sample from another is made possible by the great variability.
The Y-STR method's primary benefit is its capacity to identify the male component even in severe male-to-female DNA mixes. The number of semen donors for combinations of two or more male persons can be determined using it, as well as for quickly screening a large number of stains.
Due to their occasionally poor biostatistical efficiency and the potential to detect one or more genetic discrepancies that might potentially be explained by mutational events, STRs have a few drawbacks when examining genetic links in deficient cases.

The people of Sumer are among the earliest denizens of Mesopotamia. By about 4000 BCE, the Sumerians had organized themselves into several city-states that were spread throughout the southern part of the region. These city-states were independent of one another and were fully self-reliant centers, each surrounding a temple that was dedicated to god or goddess specific to that city-state. Each city-state was governed by a Priest King.

<h3>What is social facilitation?</h3>
The tendency for the presence of others to enhance a person's performance on a task is known as social facilitation.
Some key features of social facilitation are-
- The theory of social facilitation emerged from the study of experimental social psychology as a way to explain how people behave in social settings.
- One's dominant response can be strengthened merely by being around other people, according to the definition of social facilitation.
- An individual engages in social facilitation when they successfully perform a manageable activity in front of an audience.
- Working on a difficult activity in front of a crowd may cause arousal to rise over a healthy level and impair performance.
- A beginner on a new instrument, however, could become anxious or distracted by the pressure of performing in front of an audience, and make errors they wouldn't have made during solo practice.
