Answers
In a flowering plant hybrid called Sweat Pea or Lathyrus odoratus has blue flower more dominantly than red flower and its long pollens are dominantly seen than the round pollens.
Researcher’s result after crossing the two varieties of breed is as follows:
Round-blue and long-red plants has more frequency of around 87.4%
Long-blue and Round-red plants are seen with lesser frequency of 12.6%.
Lathyrus odoratus is a flowering plant. It is located in southern Italy and Aegean island It will grow up to 1-2 meters. This is called the sweet pea. The blue flower is taken over the red flower.
Then the high pollen is taken over the round pollen After, that the plants raised the test crossed then it observed as blue round Here, the blue round and red plants display the greater occurrence 87.4% and blue long and red round displays the lesser occurrence 12.6%.
