Title: Investigating the genetics of body shape and body colour in dragonfliesHypothesis 1) The allele which codes for gray colour is dominant over the allele which codes of brown colour.2) The allele which codes for pointy body is dominant over the allele which codes of long body.3) The genes for body colour and body shape are not linked.

Cross 1: Brown, Long x Brown, Pointy

Chi square is 0.085, d.f. =1, p=0.7702.Since p value is more than 0.05, we do not

reject the null hypothesis.

Cross 2: Brown, Long x Gray, Long

Chi square is 0.005, d.f. =1, p=0.9418.Since p value is more than 0.05, we do not

reject the null hypothesis.

Cross 3: Brown, Pointy x Gray, Long & Test cross with F1 generation

Done by: Low Chor Meng & Ganison Rajamohan

Chi square is 0.952, d.f. =3, p=0.8129.Since p value is more than 0.05, we do not

reject the null hypothesis.
