"There are many superstars from yesteryears and not all of their children are superstars. If nepotism exists everyone would have been superstars and number one.
"But the fact that today Ranveer Singh, (who) does not have mother or father who is a superstar, out of sheer talent and hard work he is where he is today. I don't think nepotism exists," Kareena said.
Karisma said being a star child was a difficult task as one has a legacy to live up to and a pressure to exceed expectations.
"It is about talent, we maybe children or grandchildren of somebody but once you are on the silver screen you are that part. When you have generations of actors and a huge legacy behind you, it is actually difficult for a star child to live up to it and succeed into this industry," she said.
"Everyone can have their own opinion and we should respect all," Karisma concluded.
Their mother Babita and actor Ranbir Kapoor's mother Neetu's career took a back seat from films after they entered the Kapoor family.
But Karisma said that they were not forced to leave the movies, it was their "choice".
"This is the myth - be it my mum or Neetu aunty. It is their choice not to work, Geeta aunty and Jennifer chose to work."
Kareena said it was her sister and her who broke the stereotypes and went on to pursue a career in films.
"It took Kapoor girls to break the norms," she said.
"My father (Randhir Kapoor) has been very supportive. He did not help us, (or) recommend us. He opened the door and told us to fly," she added.
