    *Biology Paper 5 tips*

    My friend correct me if im wrong, but monohybrid means pasing one gene (with or without tail) whereas dihybrid is passing 2 genes( like wing lenght and body colour for that dtrosphila fly stuff) right ? :( EIDT- and since they are not sex linked gender does not matter right ?

    *Biology Paper 5 tips*

    do you mind if i try to answer :p In that cross the ratio of getting no tailed to tailed is 3:1 (no tail is dominant ). Since total number of observed is 40 +72 =112, to find tail it is (1\4) * 112 and to find no tail is (3\4)*112 :D
