I had been asked this question by my school teacher while I was bunking the class.

I'd like to ask this question from Inheritance of Two Genes-1 in portion Principles of Inheritance and Variation of Biology – Class 12

Answer 1

Correct option is (a) Round green seeds

To explain: Round seeds are dominant over wrinkled seeds. Also, yellow seeds are dominant over the green seeds. Thus, the progeny of these parents will be heterozygotic resulting expression of only the dominant characters.
