| dc.description.abstract | Denisoni Barb golden (Sahyadria denisonii) merupakan ikan hias bernilai ekonomi tinggi yang ketersediaan ikannya sangat minim. Untuk meningkatkan jumlah ikan dengan fenotip golden, penelitian ini dilakukan dengan tujuan menganalisis pola pewarisan fenotip golden melalui persilangan berpasangan antara induk jantan dan betina golden dan non-golden. Skema persilangan terdiri dari pasangan golden × golden (GG) serta pasangan resiprokal golden × non golden (GN) dan non-golden × golden (NG). Analisis fenotip warna dilakukan menggunakan metode pengolahan citra digital dengan software Adobe Photoshop CS4, sedangkan pola pewarisan warna mengacu hukum Mendel dan dianalisis statistik menggunakan chi-square (khi-kuadrat) dengan selang kepercayaan 95%. Hasil penelitian menunjukkan pewarisan warna golden memenuhi asumsi Mendelian pada persilangan GG yaitu menghasilkan fenotip golden 22,4% (p > 0,05), sedangkan pada persilangan GN menghasilkan keturunan non-golden 100% yang diduga induk betina normal bergenotipe homozigot. Nisbah fenotip warna golden pada ikan Denisoni Barb mengalami perubahan setelah hari ke-90 masa pemeliharaan yang diduga dipengaruhi oleh faktor epistasis atau interaksi genetik dengan faktor lingkungan. | |
| dc.description.abstract | The golden Denison barb (Sahyadria denisonii) is a high-value ornamental fish with limited availability in the market. To increase the production of fish with the golden phenotype, this study aimed to analyze the inheritance pattern of body color phenotypes resulting from paired crossbreeding between male and female broodstock with golden and non-golden phenotypes. The crossing scheme consisted of golden × golden (GG) pairs and reciprocal crosses: golden × non-golden (GN) and non-golden × golden (NG). Phenotypic color analysis was conducted using digital image processing with Adobe Photoshop CS4, and inheritance patterns were statistically analyzed using the chi-square test based on Mendelian genetics at a 95% confidence level. Results showed that the inheritance of the golden color followed Mendelian assumptions in GG crosses, producing 22.4% golden phenotype offspring (p > 0.05). In GN crosses, 100% of the offspring were non golden, suggesting that the normal female broodstock was homozygous. The phenotypic ratio of golden color in Denison barb showed a shift after the 90th day of rearing, possibly influenced by epistasis or gene-environment interactions. | |
