Question

If round seed shape (RR) is dominant over wrinkled seed shape (rr) and yellow cotyledon is dominant (YY) over green cotyledon (yy), then in a Mendelian dihybrid cross when heterozygous round yellow seeds (RrYy) are self crossed, round green offsprings are represented by the genotype

(A) RrYy, RrYY, RRYy

(B) Rryy, RRyy, rryy

(C) rrYy, rrYY

(D) Rryy, RRyy

Answer 1

If round seed shape (RR) is dominant over wrinkled seed shape (rr) and yellow cotyledon is dominant (YY) over green cotyledon (yy), then in a Mendelian dihybrid cross when heterozygous round yellow seeds (RrYy) are self crossed, round green offsprings are represented by the genotype RRyy, RRyy.

So, The correct option of this question is (D).
