If a plant having yellow and round seeds was crossed with another plant having green and wrinkled seeds then progeny are in the ratio :

A)  15 : 1

B)  1 : 15

C)  1 : 13                                    

D)  all yellow and round seeds

Correct Answer: D

Solution :

                 Mendel crossed a dominant homozygous yellow round seeded plant with a recessive homozygous green and wrinkled seeded plant. The F, offsprings produced are heterozygous yellow round seeded plants. This cross is known as dihybrid cross. So, in F, generation, all yellow and round seeded plants are produced.
