Inheritance of Antenna Shape of Dragonflies

Hypothesis: The antenna shape follows monohybrid inheritance, where the allele of Knobbed antenna is dominant and the allele for Short antenna is recessive. . Step 2 : Mate two individuals with knobbed antenna Observed numbers: 1519 (knobbed), 481 (short) Step 3: Perform chi square test

  1. Hypothesis: The antenna shape follows monohybrid inheritance, where the allele of Knobbed antenna is dominant and the allele for Short antenna is recessive. Step 2: Mate two individuals with knobbed antenna Observed numbers: 1519 (knobbed), 481 (short) Step 3: Perform chi square test Expected: 3 (knobbed): 1 (short) Step 1: Mate two individuals with short antenna Result: all offspring has short antenna Inheritance of Antenna Shape of Dragonflies • Conclusion: • P-value is >0.05. • Do not reject Ho • deviation is not significant • follows Mendelian monohybrid inheritance of 3:1 ratio By: Florentina Widodo, Adeline Chia
