2) Consider a hairy pea plant that was grownfrom yellow seed (an F1 hybrid). This hybrid had one parent (P1)that was an inbred variety with no hairs and was grown from a greenseed. P2 was also an inbred variety, but grown from a yellow seedand had hairy leaves.
After a backcross of the F1 hybrid to the P1parent the following progeny are observed.
Yellow seed/Smooth             29
Yellow seed/Hairy                82
Green seed/Smooth               9
Green seed/Hairy                  30
a) What is the null hypothesis for the ratio ofprogenies based on the backcross described above.
b) Using a Chi square statistical test, do youreject or fail to reject the null hypothesis. Show yourcalculations.
c)Is there an easy explanation for yourconclusion?
