Show Answer
Answer : b
Hints & Solution
(b) A gynandromorph is an organism that contains both male and female characteristics. These characteristics can be seen in butterflies, where both male and female characteristics can be seen physically because of sexual dimorphism. A gynandromorph can have bilateral symmetry, one side female and one side male, or they can be mosaic, a case in which the two sexes aren’t defined as clearly.
