Human factors psychology is a branch of experimental psychology often associated with industrial/organizational psychology because it concentrates on the interaction of people and machines. Good human factors engineering can make a product convenient and easy to use, rather than frustrating and confusing.
What is Human Factors psychology?
Human Factors as a discipline was stimulated by pilot errors that cost many lives during World War II. Analysis of flying accidents revealed that many were due to the confusing layout of instruments in airplane cockpits. Pilots were faced with a bewildering array of dials and gauges in the cockpit, yet they were expected to keep track of all pertinent information and respond appropriately in emergencies. Human Factors psychologists helped to identify problems in cockpit design. They attempted to design instrument panels that were clear and easy to use for humans.
No genetic or physical maps of the genome are needed to begin shotgun cloning and is much faster.
<h3>What is Shotgun cloning?</h3>
This is a method to duplicate genomic DNA in which it is smashed into small pieces and the fragments are then taken together and cloned into a vector.
This type of cloning however is faster as there are no genetic or physical maps needed to begin the process.

<h2>Down Syndrome</h2>
Explanation:
Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
- Down syndrome is a genetic disorder caused when abnormal cell division results in an extra full or partial copy of chromosome 21
- Down syndrome is usually caused by an error in cell division called nondisjunction which results in an embryo with three copies of chromosome 21 instead of the usual two
- Prior to or at conception, a pair of 21st chromosomes in either the sperm or the egg fails to separates
- With development in embryo the extra chromosome is replicated in every cell of the body;this type of Down syndrome which accounts for 95% of cases is called trisomy 21
- Maternal age is the only factor that has been linked to an increased chance of having a baby with Down syndrome resulting from nondisjunction;here environmental agents such as drugs, chemicals, and radiation act as mutagens which induce mutation in the fetus
