Number of eggs laid by native and introduced Drosophila subobscura females during test phases after a learning task

Header consists in : Date (day of start of the experiment), Type ("I" = Introduced, "N" = Native population),Pop (Population of origin),Cond ("B/FQ" : learning phase to avoid strawberry, "BQ/F" : learning phase to avoid banana), Test (Number of test phase), milieu.B (number of eggs laid in banana medium), milieu.F (number of eggs laid in strawberry medium), tot (total number of eggs laid),propB (proportion of eggs laid in the banana medium), propG (proportion of eggs laid in the correct medium), Lat (Latitdue of the populaiton of origin)
