What may be the characters that will appear in the plants produced as a result of the self pollination of the first generation?

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:

EASY
A pure breeding pea plant with round yellow seeds was crossed with pea plant having wrinkled green seeds. On selfing of F1, hybrid of his cross, 64 progenies were obtained in F2 generation. Find out the number of F2 progenies showing non-parental characters.
