(Augustinian Monastery of St. Thomas, Brno, Czech Republic)
in a greenhouse and in outdoor garden plots. A statue of
appears in the background. The garden plot shown here
laid out as a series of crosses between flowers. The parental
plants (P) have red and
flowers (top row). From these
and white-flowered plants, the F1 is
uniformly red (second
row). The third row shows the result of an F2
cross: note the 3:1 ratio
red to white flowers. The remaining four
rows show the result of a dihybird cross: it is possible to
discern Tall and Short phenotypes.
Homework: Evaluate the
results of the dihybrid cross. Is
there anything unusual about the results?
