Huu hapa ni ufumbuzi wa swali lako: Step 1: Tambua jeni za wazazi. Kutokana na maelezo, "widow's peak" ni sifa kuu (dominant) na "frontal hairline" ni sifa fiche (recessive). Tunatumia B kwa "widow's peak" na b kwa "frontal hairline". Mwanamume mwenye "homozygous widow's peak" ana jeni BB. Mwanamke mwenye "homozygous frontal hairline" ana jeni bb. Step 2: Tambua gameti zinazozalishwa na kila mzazi. Mwanamume (BB) atazalisha gameti zote zenye B. Mwanamke (bb) atazalisha gameti zote zenye b. Step 3: Tumia mraba wa Punnett kubainisha jeni za kizazi cha F1. |c|c| Gameti & B \\ b & Bb \\ Kizazi cha F1 kitakuwa na jeni Bb. Step 4: Tambua fenotipu ya kizazi cha F1. Kwa kuwa B ni sifa kuu, viumbe vyote vyenye jeni Bb vitaonyesha sifa ya "widow's peak". Kizazi cha F1: Genotype: Bb Phenotype: Widow's peak Tuma swali linalofuata 📸
