  1. Inheritance of Antennae Shape and Leg Colour in Dragon FliesSunny Ho, Yip Cheng Wai, Lena Koh, Chan Hwee Sing Hypothesis: The alleles for knobbed antennae & red legs are dominant, gives a 9:3:3:1 ratio when two heterozygotes are crossed. Chi square value = 1.648 With 3 deg of freedom P= 0.6486 P> 0.05, therefore accept hypothesis. There is a 9:3:3:1 ratio. Knobbed red is dominant to Pointy brown Description of experimental crosses: Knobbed red male x knobbed red female Data and Data Analysis:
