Hechose peas because they had been used for similar studies, are easy to grow and can be sown each year.Pea flowers contain both male and female parts, called stamen and stigma, and usually self-pollinateMendel used seven pea plant traitsin his experiments which include flower color (purple or white), flower position (axil or terminal), stem length (long or short), seed shape (round or wrinkled), seed color (yellow or green), pod shape (inflated or constricted), and pod color (yellow or green).
Answer- The above question is from the chapter 'Heredity and Evolution'.
Given question: State the reasons to choose pea plants by Mendel for his experiments and mention the seven contrasting characters chosen by him.
Answer: Following are the reasons why Mendel chose pea plants for his experiment-
1) They have short life-span. Thus, many generations can be studied easily.
2) They produce many seeds at a time.
3) They have seven contrasting features.
4) They have bisexual flowers.
5) They undergo self-pollination.
Seven contrasting characters are-
1) Seeds: Round and Wrinkled
2) Flowers: Violet and White
3) Colour of seeds: Yellow and Green
4) Height: Tall and Short
5) Position of flowers: Axial and Terminal
6) Pod colour: Yellow and Green
7) Pod shape: Constricted and Inflated
