1. Differentiation of sex is best possible by:
- Pelvis
- Femur
- Humerus
- Tibia
Answer
Answer: (1) Pelvis
2. Pubic angle of pelvis griddle in female is
- Right angle
- Obtuse angle
- Acute angle
- None of these
Answer
Answer: (2) Obtuse angle
3. The public angle of pelvis girdle of male is:
- Acute
- Normal
- Obtuse
- None of these
Answer and Explanation
Answer: (1) Acute
Explanation:
-> In male, the subpubic angle is 70° to 75° (V-shaped/ acute angle).
-> In females, the subpubic angle is 90° to 100° (U shaped/ obtuse angle).
4. Which bone helps to accurately determine gender in a fetus?
- Femur
- Skull
- Sacrum
- Hip bone
Answer and Explanation
Answer: (3) Sacrum
Explanation: With the Sacrum ilium bone, 100% accuracy in the determination of fetal sex is seen whose age is more than 22 weeks from severely mutilated and decomposed bodies during postmortem examination.

5. Which is the best feature of the Pelvis bone that helps in accurate gender identification?
- Subpubic angle
- Greater sciatic notch
- Inverted Ischial tuberosity
- Everted Ischial pubic rami
Answer and Explanation
Answer: (1) Subpubic angle
Explanation: With the subpubic angle, the accuracy is about 90.8% for gender determination.
-> In male, the subpubic angle is 70° to 75° (V-shaped/ acute angle).
-> In females, the subpubic angle is 90° to 100° (U shaped/ obtuse angle).
6. Washburn’s index helps in the determination of
- Age
- Gender
- Stature
- Race
Answer and Explanation
Answer: (2) Gender
Explanation: Washburn’s Index, also called the Ischiopubic index, is a gender determination index based on the length of pubis and ischium.
Washburn Index= (Length of Pubis/ Length of ischium) x 100
-> If the resultant value is in-between 73 to 94= male.
-> If values falls in between 91 to 115= female
7. Which of the following features of the hip bone is most accurate for determination of gender?
- Ischial tuberosity
- Greater sciatic notch
- Ischiopubic ramus
- Iliac crest
Answer and Explanation
Answer: (3) Ischiopubic ramus
Explanation: Ischiopubic Ramus for females: Not everted and for males: Everted
8. Assertion (A): Individualization can be done from buccal mucosal cells.
Reason (R): Because of the presence of Barr bodies.
Codes:
- Both (A) and (R) are correct.
- Both (A) and (R) are incorrect.
- (A) is correct, but (R) is incorrect.
- (R) is correct, but (A) is incorrect.
Answer and Explanation
Answer: (3) (A) is correct, but (R) is incorrect
Correct Reason: With the help of buccal mucosal cells, DNA analysis can be done to establish individuality. And Barr bodies are a test for the determination of gender.
9. The following is not a feature of a female skull:
- Prominent parietal eminence
- Prominent frontal eminence
- Prominent glabella
- Roundish shaped orbits
Answer
Answer: (3) Prominent glabella
10. The accuracy of sex determination from pelvis is
- 80%
- 85%
- 90%
- 95%
Answer and Explanation
Answer: (4) 95%
Explanation: Accuracy of sexing based on skeletal remains:
-> Entire skeleton: 100%
-> Skull + Pelvis: 98%
-> Long bones + Pelvis: 98%
-> Pelvis: 95%
-> Skull: 92%
-> Long bones: 80–85%
11. The shape of sub-pubic-angle in a female is:
- L shaped
- U shaped
- V shaped
- Round shape
Answer and Explanation
Answer: (2) U shaped
Explanation: With the subpubic angle, distinction between male and female can be determined with an accuracy of 90.8%.
-> In male, the subpubic angle is 70° to 75° (V-shaped/ acute angle).
-> In females, the subpubic angle is 90° to 100° (U shaped/ obtuse angle).
12. The following are the features of a female pelvis except:
- Wide greater sciatic notch
- Prominent preauricular sulcus
- Triangular obturator foramen
- Triangular shaped pubic bone
Answer and Explanation
Answer: (4) Triangular shaped pubic bone
Explanation: Females have U-shaped public bone with a subpubic angle in-between 90° to 100°.
13. Preauricular Sulcus helps in the determination of:
- Age
- Gender
- Stature
- Race
Answer and Explanation
Answer: (2) Gender
Explanation: The preauricular sulcus is a characteristic of the female pelvis who had given birth to the infant. They have anterior sacroiliac ligament which is prominent due to obstetrical trauma during the course of delivery.
14. Which of the following is not a prominent feature of male skull?
- Glabella
- Frontal eminence
- Supraorbital ridge
- Zygomatic arch
Answer and Explanation
Answer: (2) Frontal eminence
Explanation: Frontal eminence (or tuber frontale) is less prominent in males and more prominent in females.
15. Foramen magnum is present on:
- Pelvis
- Scapula
- Sternum
- Skull
Answer and Explanation
Answer: (4) Skull
Explanation: Foramen magnum (in Latin means “great hole”) is a large oval opening (foramen) in the occipital bone present in the base of the skull.
