I have 2 tables, the first called GenotypesMaleUp

    GenotypesMaleUp = {2.04545, 1.80196, 1.70542, 1.78403, 1.79929, 1.91629, 1.82785, \
    1.52171, 1.9913, 1.43151, 1.96283, 1.44868, 2.11816, 2.03117, \
    2.16076, 1.55718, 1.74599, 2.41115, 1.96451, 2.20853}

and the second called SurvivorsMaleUp

    SurvivorsMaleUp = {0.989309, 0, 0.636673, 0, 0.810913, 0.964202, 0.857113, 0, 0.999606, \
    0, 0, 0.350838, 0, 0, 0, 0, 0, 0.414982, 0.99347, 0.79752}

They are both the same length. I want to join the first term of GenotypesMaleUp with the first term of SurvivorsMaleUp, and so on for each other term so it would look like

    {2.04545,0.989309}, {1.80196,0},(1.70542,0.636673},...

I tried `Table[{GenotypesMaleUp, SurvivorsMaleUp}, 1]` but got

    {{{2.04545, 1.80196, 1.70542, 1.78403, 1.79929, 1.91629, 1.82785, 
       1.52171, 1.9913, 1.43151, 1.96283, 1.44868, 2.11816, 2.03117, 
       2.16076, 1.55718, 1.74599, 2.41115, 1.96451, 2.20853}, {0.989309, 
       0, 0.636673, 0, 0.810913, 0.964202, 0.857113, 0, 0.999606, 0, 0, 
       0.350838, 0, 0, 0, 0, 0, 0.414982, 0.99347, 0.79752}}}

as the output, so it just joined the lists together at the end of the first and beginning of the second list.
