Title: Investigating the genetics of body shape and body colour in dragonflies

Title: Investigating the genetics of body shape and body colour in dragonflies. Hypothesis 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.
