Important Questions on Principles of inheritance and Variation

MEDIUM

Given below are two statements:
Statement I: Mendel studied seven pairs of contrasting traits in pea plants and proposed the Laws of Inheritance.
Statement II: Seven characters examined by Mendel in his experiment on pea plants were seed shape and colour, flower colour, pod shape and colour, flower position and stem height.
In light of the above statements, choose the correct answer from the options given below:
