Lucas conducted a dihybrid cross in his genetics experiment. He observed 315 flies with gray body and long wings, 108 flies with gray body and miniature wings, 101 flies with ebony body and long wings, and 32 flies with ebony body and miniature wings. Analyse these data using x test to see if (i) they fit a 9:3:3:1 ratio. (ii) the gray : ebony data fit a 3:1 ratio.
