Sex Chromosome Composition
| Animal | Chromosome Composition |
|---|---|
| Poultry Female | 76 + ZW (heterogametic) |
| Human Male | 44 + XY (heterogametic) |
| Poultry Male | 76 + ZZ (homogametic) |
| Human Female | 44 + XX (homogametic) |
Total chromosomes in poultry (chicken): 78 (76 autosomes + 2 sex chromosomes). Total chromosomes in humans: 46 (44 autosomes + 2 sex chromosomes).
