Question

In Mendelian dihybrid cross, when heterozygous Round Yellow are self crossed, Round Green offsprings are represented by the genotype

Answer 1

Answer:

The genotype of the F

1

plants is RrYy. These plants were self-crossed by Mendel. In his dihybrid cross the F

2

plants were obtained in the phenotypic ratio 9 (round yellow):3 (round green) :3 (wrinkled yellow):1 (wrinkled green) as shown in the Punnett square. Round seeds can be represented by the genotype RR or Rr as roundness of the seed is a dominant trait and can be homozygous or heterozygous. The green color is homozygous recessive and can be represented as yy. Thus the correct answer is option D.
