Pada kacang, bunga ungu dominan (UU) terhadap bunga putih (uu). pada persilangan tersebut didapat F1 berbunga ungu heterozigot (Uu). Jika F1 disilangkan sesamanya menghasilkan F2 sebanyak 80 tanaman. berapa : (a) perbandingan fenotipe nya? (b) perbandingan Genotipe nya? (c) jumlah F2 yang berwarna ungu?

18 5 ​ / 72 25 ​ ∗ 100% = 18 5 ​ ∗ 25 72 ​ ∗ 100% = 18 ∗ 25 5 ∗ 72 ​ ∗ 100% = 2 ∗ 5 1 ∗ 8 ​ ∗ 100% = = 1 8 ​ ∗ 10% = 8 ∗ 10% = 80%

To find what percentage 18 5 ​ is of 72 25 ​ , divide the first fraction by the second and multiply by 100. The calculation shows that 18 5 ​ is 80% of 72 25 ​ .

Jawaban:✅ (a) Perbandingan fenotipe (bunga ungu : putih)= 3 : 1✅ (b) Perbandingan genotipe (UU : Uu : uu)= 1 : 2 : 1✅ (c) Jumlah F2 yang berwarna ungu dari 80 tanaman= (3/4) × 80 = 60 tanamanPenjelasan singkat:Persilangan:Uu × Uu →Hasil:UU, Uu, Uu, uuFenotipe: Ungu (UU, Uu, Uu) : Putih (uu) = 3 : 1Genotipe: UU : Uu : uu = 1 : 2 : 1Jumlah ungu = ¾ × 80 = 60 tanaman
