Developing fly larvae (egg) express Hox genes that work in a similar manner to those in mammals. Below is a diagram of the larvae Hox gene expression and phenotype. Choose from the drop down menus to finish the sentence correctly based on the image provided. 3pts “A fly that has loss of function of Hox gene scr, would create a fly that has no [option1], but has an extra set of [option2] in position [option3].”
