Genetics plays an important role in how our personalities develop, but it isn't the only thing that matters. Here’s a simple breakdown:

1. Genetic Influences:

   • Some traits, like how we show our emotions, can be passed down from our parents.
   • Research shows that traits like being shy or outgoing might come from our genes for about 40-50%.

2. Environmental Factors:

   • How we grow up, the way we are raised, and our culture all affect our personality.
   • For instance, two siblings can have the same genes, but they might turn out very differently because of their unique life experiences.

In the end, genetics and our surroundings work together to shape a child's personality. It’s like a team effort between nature and nurture!
