- 3. The inheritance of petal color in some plant species is alleged to be codominant. A group of pure (homozygous) white carnations were deliberately pollinated with pollen from pure red carnations. Fertilized seeds were collected, and after germination and growth of this F1 generation, they were allowed to freely pollinate one another. The color of the flower on each plant in the F2 generation was tallied. 239 red, 307 white, and 615 pink plants were recorded. Apply a ?2 analysis to determine the statistical validity of the assumed inheritance pattern. Show every step in your thought process along with all relevant calculations and written support. HINT: For this problem, you should DEFINITELY construct the two Punnett squares to reveal the phenotypes of the F1 and F2 generations.

However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination.
