The number of blue plants expected is 
The number of red plants expected is 
The anticipated number of violet plants is 
Calculated chi square value
Explanation:
Frequency of blue allele is
Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

Frequency of other allele

Chi Square test

Plants found in cold environments have a higher amount of photosynthesis at low temperatures. Plants in warm environments, have a higher photosynthesis in high temperatures.
Photosynthesis is the process by which plants make their food from sunlight . This process is mostly dependent on sunlight so it varies from temperature and seasons. Greater light intensity leads to higher photosynthesis rates, as does increased carbon dioxide concentration.
Photosynthesis is generally higher during early summer and decline by autumn season . Temperature also plays an important role in photosynthesis as temperature increases the number of collisions increases, therefore the rate of photosynthesis also increases.
