- 1.
This is:
- A.
A chromosome
- B.
A Karyotype
- C.
F.I.S.H
Correct Answer
B. A KaryotypeExplanation
A karyotype is a visual representation of an individual's chromosomes, arranged in pairs and organized by size and shape. It allows for the identification of any abnormalities or genetic disorders, as well as the determination of an individual's sex. This answer is correct because it accurately identifies the given image as a karyotype, which is a common diagnostic tool used in genetics and cytogenetics.Rate this question:

This is an example of:
- A.
The structure of a cell
- B.
The mapping system
- C.
A Karyotype
- D.
An abnormal chromosome
Correct Answer
B. The mapping systemExplanation
The correct answer is "The mapping system." This is because the question is asking for an example, and the other options (the structure of a cell, a karyotype, and an abnormal chromosome) are not examples of anything. The mapping system, on the other hand, is a specific example that can be used to explain or illustrate a concept or process.Rate this question:

The most important technology used in cytogenetics is:
- A.
Microscopes
- B.
Centrifuges
- C.
F.I.S.H.
- D.
Karyotypes
- E.
Test Tubes
Correct Answer
C. F.I.S.H.Explanation
F.I.S.H. stands for fluorescence in situ hybridization, which is a technique used in cytogenetics to detect and locate specific DNA sequences on chromosomes. It involves the use of fluorescent probes that bind to specific DNA sequences, allowing researchers to visualize and analyze the chromosomes under a microscope. F.I.S.H. is a crucial technology in cytogenetics as it helps in the diagnosis of genetic disorders, identification of chromosomal abnormalities, and understanding the organization and behavior of chromosomes.Rate this question:

Down syndrome comes from:
- A.
A deletion in the 21st chromsome
- B.
A copy of the 21st chromosome
- C.
The 21st chromosome attaching to the 23rd chromosome
- D.
The deletion of the 20th chromosme
- E.
None of the Above.
Correct Answer
B. A copy of the 21st chromosomeExplanation
Down syndrome is caused by the presence of an extra copy of the 21st chromosome. This additional genetic material disrupts the normal development and causes the characteristic physical and cognitive features of Down syndrome.Rate this question:

Cytogenetics has been around since:
- A.
The 18th Century
- B.
The 19th Century
- C.
The 20th Century
- D.
The 21 Century
- E.
None of the above
Correct Answer
C. The 20th CenturyExplanation
Cytogenetics is the study of chromosomes and their abnormalities, which involves analyzing the structure, function, and behavior of these genetic materials. The field of cytogenetics began to develop in the early 20th century with the discovery of chromosomes and their role in heredity. Scientists such as Thomas Hunt Morgan and Theophilus Painter made significant contributions to cytogenetics during this time. Therefore, the correct answer is "The 20th Century."Rate this question:

This is an Karyotype from a:
- A.
Male
- B.
Woman
Correct Answer
A. MaleExplanation
The given karyotype is from a male because males typically have XY sex chromosomes, whereas females have XX sex chromosomes. The karyotype shows a pair of XY chromosomes, indicating that the individual is male.Rate this question:
