2 Answer

  • C is correct. Both factors matter in terms of multigenic traits like size. 
  • The correct answer is option C

    The size of the organisms is most likely determined by its environment and genes. The size of the organism is dependent on the genes as it depends on the size of their parents but some times the environmental conditions also helps in the determining the size of the organism. There are certain examples present in the environment that can help us to understand this statement.

    Example: The giraffe were small in size but when there was no plants(food) left that were small in size, in this condition they adapted the environmental conditions and evolved into larger size.
