TABLE-I (Animal) TABLE-II (Sex Chromosomes)
1. Poultry female a. 76 + ZZ
2. Human male b. 76 + ZW
3. Poultry male c. 44 + XX
4. Human female d. 44 + XY
- 1-a, 2-b, 3-c, 4-d
- 1-b, 2-d, 3-a, 4-c — Correct Answer
- 1-b, 2-c, 3-a, 4-d
- 1-a, 2-d, 3-b, 4-c
Explanation:
Correct Answer: 1-b, 2-d, 3-a, 4-c
Sex Chromosome Constitution
| Animal | Sex Chromosomes |
|---|---|
| Poultry female | 76 + ZW (heterogametic) |
| Human male | 44 + XY (heterogametic) |
| Poultry male | 76 + ZZ (homogametic) |
| Human female | 44 + XX (homogametic) |
Key rule: In mammals (humans, cattle, pigs), the male is heterogametic (XY). In birds (poultry), the female is heterogametic (ZW).
