Answer 1

The correct option is B Two sexes of same species shows different characters

Sexual dimorphism is observed in two sexes of the same organism. The two sexes, male and female show difference in many of their characters. There are differences observed in the reproductive organs. They also exhibit differences in their physical appearance, behaviour, etc. These organisms show difference in the traits like the colour of feathers, pattern of feathers in birds, presence of horns in cattle, presence of wings in butterfly, etc. These characters help in distinguishing the male and the female organisms of the same species.

Thus, the correct answer is option B.
