How many total chromosomes does a normal human female karyotype display?
- A.
23
- B.
46
- C.
96
- D.
128
Correct Answer
B. 46Explanation
A normal human female karyotype displays a total of 46 chromosomes. This is because humans have 23 pairs of chromosomes, with one set inherited from each parent. In females, one of the pairs is made up of two X chromosomes, known as the sex chromosomes, while the other 22 pairs are autosomes. Therefore, the correct answer is 46.Rate this question:

How many total chromosomes does a normal human male karyotype display?
- A.
23
- B.
46
- C.
96
- D.
128
Correct Answer
B. 46Explanation
A normal human male karyotype displays a total of 46 chromosomes. This is because human cells typically contain 23 pairs of chromosomes, with one set inherited from the mother and one set inherited from the father. In males, one pair of these chromosomes is the sex chromosomes, consisting of one X and one Y chromosome, determining the individual's male characteristics. The remaining 22 pairs are the autosomes, which contain genes responsible for various traits and characteristics. Therefore, the correct answer is 46.Rate this question:

- D.
48
Correct Answer
B. 45Explanation
A normal human karyotype consists of 46 chromosomes, with 23 pairs. However, in Turner's Syndrome, there is a missing or incomplete X chromosome in females. This results in a total of 45 chromosomes instead of the usual 46. Therefore, the correct answer is 45.Rate this question:

- E.
4
Correct Answer
B. 1Explanation
A Turner's Syndrome karyotype typically displays only one sex chromosome. This condition is characterized by the absence of one X chromosome in females, resulting in a karyotype of 45,X. Normally, females have two X chromosomes (46,XX), but in Turner's Syndrome, there is a monosomy of the sex chromosomes, leading to various physical and developmental abnormalities. Therefore, the correct answer is 1.Rate this question:

Correct Answer
47Explanation
A person with Down's Syndrome has an extra copy of chromosome 21, known as trisomy 21. Normally, individuals have 46 chromosomes, but in the case of Down's Syndrome, there is an additional chromosome, resulting in a total of 47 chromosomes.Rate this question:

Trisomy - 13
- C.
Trisomy - 15
- D.
Trisomy - 18
- E.
Trisomy - 21
Correct Answer
E. Trisomy - 21Explanation
Trisomy refers to the presence of an extra copy of a chromosome in a person's cells. In the case of Down's Syndrome, it is caused by the presence of an extra copy of chromosome 21. Therefore, the secondary name for Down's Syndrome is Trisomy - 21.Rate this question:

What was the former name of Down's Syndrome?
- A.
Patau's Disease
- B.
Mongolism
- C.
Defreuss
- D.
Hardy - Stevens
Correct Answer
B. MongolismExplanation
The former name of Down's Syndrome was "Mongolism." This term was used in the past to describe the condition because individuals with Down's Syndrome were thought to resemble the facial features of individuals from Mongolia. However, this term is now considered outdated and offensive, as it perpetuates stereotypes and is not medically accurate. The condition is now universally referred to as Down's Syndrome, named after the physician John Langdon Down who first described it in the 19th century.Rate this question:

Individuals with Trisomy - 13 survive fetal development are born Severely mentally retarded and physically malformed.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Individuals with Trisomy-13, also known as Patau syndrome, typically have severe intellectual disabilities and physical abnormalities. Trisomy-13 is caused by the presence of an extra copy of chromosome 13, which disrupts normal development. Babies with this condition often have heart defects, cleft lip or palate, and other structural abnormalities. They may also experience vision and hearing problems, seizures, and difficulty feeding. Sadly, the prognosis for individuals with Trisomy-13 is generally poor, with many not surviving beyond infancy or early childhood. Therefore, the statement "Individuals with Trisomy-13 survive fetal development are born severely mentally retarded and physically malformed" is true.Rate this question:

Correct Answer
C. Male , XExplanation
XXY syndrome, also known as Klinefelter syndrome, is a genetic condition that affects males. It occurs when a male has an extra X chromosome, resulting in a total of 47 chromosomes instead of the usual 46. This condition can cause various physical and developmental differences, such as infertility, low testosterone levels, and learning disabilities. Therefore, the correct answer is "Male, X" as it accurately describes the genetic condition.Rate this question:

The genetic condition called 46, XX, der (4) t(4,8) (q35.1;q 24:11). Which statement is correct?
- A.
Chromosome 4 is normal
- B.
Chromosome 4 lost part of it's arm
- C.
Chromosome 6 is normal
- D.
Chromosome 8 is normal
Correct Answer
B. Chromosome 4 lost part of it's armExplanation
The correct answer is "Chromosome 4 lost part of its arm." This is indicated by the presence of the der(4) in the given genetic condition. The der(4) refers to a derivative chromosome 4, which means that there has been a rearrangement or loss of genetic material from chromosome 4.Rate this question:

- D.
Duplicated
Correct Answer
C. DerivedExplanation
The term "der" in the genetic condition 46, XX, der (4) t(4,8) (q35.1;q 24:11) refers to "derived." In genetics, "derived" is used to describe a chromosome or genetic material that has undergone rearrangements or changes, resulting in a new structure or configuration. In this case, the "der" indicates that there has been a rearrangement involving chromosome 4, specifically a translocation between chromosomes 4 and 8.Rate this question:
