    I think poly genetic traits is talking about skin color or the height in human where these traits are controlled by more than one gene ( 2 alleles ) such as white skin the genes are d1d1d2d2d3d3/ skin with darker color the genes become d1d1D2D2D3D3/ but the black skin the genes will be D1D1D2D2D3D3 https://www.google.com/search?newwindow=1&hl=en-QA&authuser=0&biw=1366&bih=608&tbm=isch&sa=1&ei=BXKsXKKQM5io1fAPtMa3-Ak&q=polygenic+trait&oq=poly+geneic+&gs_l=img.1.0.0i10i24.316805.320489..323112...0.0..0.315.2522.0j6j5j1......1....1..gws-wiz-img.......0i67j0j35i39j0i10j0i5i30j0i8i30j0i30.aZgRuPpS_zI#imgrc=9_m48u9PPT2ceM:
