A Visit From the Snow Geese

ClaireAnna took all these pictures today.  You can double click to enlarge them.  This is the first time we’ve seen a whole flock of Snow Geese on the farm.  P2100324 P2100326 P2100327 P2100307  P2100313  P2100319
Today we’ve learned that Snow Geese come in two colors: white or blue/ grey.  The grey coloring is from a single dominant gene.  The white bird is homozygous for white.  Birds of either sex can be either color.  Mated pairs tend to be the same coloring but not always.  ClaireAnna’s made Punet squares to see what coloring the offspring will be based on the genetics of their parents.  scan0001
