Dominant = Dark color Recessive = Light color Mom Dad Possible offspring genotypes and phenotypes dd dd (100%) = light DD DD (100%) = dark Dd (100%) = dark Dd DD (50%) or Dd (50%) = all dark Dd (50%) = dark, dd (50%) = light DD (25%), Dd (50%) = dark (75%) dd (25%) = light

Male XY Has a tie. Female XX Has a bow. Possible Traits Dominant Recessive Color – “D” Dark Light Eyes – “R” Round Square Nose – “T” Triangular Oval Teeth – “S” Pointed Hair - “C” Curly Straight
