Solution

The correct option is A

Round yellow seeds


  • Yellow colour of pea seeds is dominant over green color and round shape of pea seeds is dominant over wrinkled ones.
  • A cross between pure yellow round seeded plants (YYRR) and green wrinkled seeded plants (yyrr) would yield heterozygous plants with yellow round seeds (YyRr) in the F1 generation.
